What will be the probability that z is greater than 1. 75? 0. 0401 z end up in the higher than 1. 75. 22) A null hypothesis will make a claim about what? A Population parameter Explanation: A null hypothesis is the general default position in a survey and requires a claim off population parameter. 23) Describe the level of significance? Probability off Type I error Explanation: A type 1 error happens when the null hypothesis is true, but rejected at he same time. 24) Let's perform a statistical test of the difference between two proportions at the 0. 05 level of significance.If the computed z is -1. 07, what will be the correct decision? Do not reject the null hypothesis. Explanation: The z is of -1. 07 is acceptable within the range of a . 05 level of significance. 25) What condition must be met to perform a test for the difference of two sample means? Data must be at least of interval scale and populations must be normal. 26) Consider a hypothesis test that compares two population means. The combined degrees of freedom equal 24. What statement about the sample sizes is NOT true? Let's assume the population standard deviations are equal. Sample A = 11.Sample B = 13 Explanation: This must NOT be true because it is outside the limits set by the degree of freedom. 27) What type of chart do we call it when paired data is plotted? Scatter diagram Explanation: Paired data must be plotted in a way that shows the relationship 28) When a variable is used to predict the value of another variable, it is called: Independent variable Explanation: The independent variable is useful for determining the values of variables that are not explicitly known. 29) 20 randomly selected online students were given 1 5 multiple-choice problems ND 15 open-ended problems that cover the same topics.The teacher wanted to know which questions the students scored better on. What kind of test is this? A paired t-test Explanation: The paired t-test evaluates the mean values that result form a s et of data. 30) The weights of 100 units of a product created by two identical processes have same mean, but the standard of process A is 15 while that of B is 7. What is true about this scenario? Unit weights in process B will be grouped closer than in process A. Explanation: A wider standard of process is going to create greater deviation in the end products.

Compare and contrast the short stories “Mr. Loveday’s Little outing” by Evelyn Waugh, and “Raspberry Jam” by Angus Wilson

In this essay I will introduce, compare and contrast two short stories, written in rather similar ways but with some very important differences. The first of these stories is â€Å"Mr. Loveday's Little outing† by Evelyn Waugh, the second, â€Å"Raspberry Jam† by Angus Wilson. Upon initial inspection of the introductory paragraphs of these two short stories it becomes apparent that Raspberry Jam is far more complex than its counterpart, and is also considerably longer. It is introduced in a fashion not unlike that of a novel, with a lot of dialogue and insight into the primary character; Johnnie's thoughts and his family's perceptions of him. The scene is set in the opening sentence â€Å"‘How are your funny friends from Potter's Farm, Johnnie?' asked his aunt from London.† We are introduced to two characters, the central character and his aunt, who appears, through her discourse as being rather posh and self-important. The story then continues with narrative giving insight into Johnnie's take on things. We immediately notice the retrospective style of writing as Johnnie recounts past events regarding his family and particularly his two elder friends; Misses Swindales, of whom his close relatives do not approve. Through their conversation we come to understand that they regard the old women as somewhat strange, â€Å"mad† even; â€Å"you really must meet them. They're the most wonderful pair of freaks.† Subsequently, through Johnnie's uneasy reaction to this talk â€Å"Many of the things the others said made the little boy bite his lip† we understand that the story is about madness, and each character's own definition of â€Å"mad† with regards to the class structure of the time.Love Poem The second story, â€Å"Mr. Loveday's Little outing† opens in a rather different manner, the first phrase â€Å"You will not find your father greatly changed,' remarked Lady Moping, as the car turned into the gates of the County Asylum.†, introduces us to, yet another rather genteel woman, Lady Moping, who is engaged in conversation with her daughter, Angela. They are going to visit Lord Moping, Angela's father in the County Asylum and again, through the latter's wife's manner of speech we can see that she does not approve of her husband being in an Asylum. The narrative technique, here is a progressive one, and thus the story is kept much less complex, with fewer mental insights, and a much more superficial approach. Although the narrative techniques and simplicity of plot and characters is distinctively different across the two stories, the main characters themselves are parallel. In both â€Å"Raspberry Jam† and â€Å"Mr. Loveday†¦Ã¢â‚¬  there is a conflict in the class structure, in the first, this is apparent through Johnnie/his relatives and in the latter, through Angela/Lady Moping. A parallel can be drawn between Johnnie and Angela as two children who seem to be thoroughly uninterested in the class system and appear to be trying to break free from it in their own ways. Johnnie is a rebel, drawing disapproval from his parents as his father is â€Å"always complaining that the child is too much with women and has no friends his own age.† Angela, on the other hand, associates herself with inmates at the asylum â€Å"Angela left the asylum, oppressed by a sense of injustice. Her mother was unsympathetic †¦ ‘He attempted to hang himself in the orangery,' replied Lady Moping, ‘in front of the Chester-Martins.' The situation of each child is very like the other's, with the parents disapproving of their children's actions on the grounds of a violation of the class structure. The biggest similarity, across the two stories lies in the fact that each and every character in both of the stories thinks that someone is mad and the plot itself is about their different perceptions of ‘mad'. In â€Å"Raspberry Jam†, for example, Grace thinks that the Misses Swindales are mad, but they, on the other hand, perceive the world as being mad, and occasionally even, each other. Both stories are therefore spinning a web of confusion and madness within which all the characters are trapped and trying to make sense of. The biggest similarity between these two short stories, however, is certainly their conclusion. Each has a ‘dormant' character that reveals themselves towards the end, having deceived the reader and the other characters for the length of the book. In â€Å"Raspberry Jam† this is the Misses Swindales, whom everyone thinks to be mad, but do not appear to be until the end when, in the presence of Johnnie, they sadistically butcher a bullfinch. In â€Å"Mr. Loveday's Little Outing†, Mr. Loveday himself is the twist in the story, when, after appearing perfectly sane for twenty years, he murders a young woman on a bicycle, repeating his previous crime and making of himself a serial killer. Finally, â€Å"Mr. Loveday's Little Outing† is much more light-hearted than its counterpart; â€Å"Raspberry Jam† which is full of physiological black humour. The latter is therefore much ‘heavier' and more sinister with regards to both the events and the style of writing. Despite the fact that Evelyn Waugh's story deals with such grim matters as suicide, it is presented in a rather comical manner â€Å"Lord Moping habitually threatened suicide on the occasion of the garden party†. It must also not be forgotten that each of these stories is a small masterpiece, each following the same template but having been written in completely different styles. Neither is superior, it is purely a matter of preference of literary styles, be it progressive or retrospective, comical or grim, each style adds a different flavour to the plot and the way in which we, the reader interpret the events.

Change Management in Delta Airlines Research Paper

Change Management in Delta Airlines - Research Paper Example The next portion of the project would be dealing with the diagnosis of the business conditions of Delta Airlines. This part would be discussing the mission and vision statement of the company followed by its objectives and business strategies.

The Eight Step Model of Kotter is one of the most popular models for scheduling, implementing and finally sustaining a change process. Company Overview As already discussed above, Delta Airlines is a popular American Airline whose headquarter is located in Atlanta, United States (Federal Aviation Administration, 2013). This airline generally operates both international and domestic networks having its service routes in all the continents excepting Antarctica. The company along with its subsidiaries operates more than 5000 flights regularly. The company employs 80000 employees approximately (Delta Air lines, n.d.). The hub is located at Hartsfield Jackson Atlanta International Airport, which is one of the busiest airports in the world, in terms of passenger traffic as well as the total number of takeoffs and landings. It is the sixth oldest international airline because of its foundation date. Moreover, it is one of the oldest airways in United States as well. The company is one among the 4 founding members of Sky Team Airline Alliance, the other 3 being Air France, Aeromexico and Korean Air. The company has been declared as the largest airline in the world in 2011and 2012 in terms of the total fleet size and the scheduled passenger traffic (Rediff, 2013). It has also been rewarded for becoming the second largest airline in respect of the total revenue-passenger kilometers carried in the year 2012. The Delta Connection provides regional service to the company. Diagnosis The foundation of the company is based on the reliable and safe air transportation, providing differentiated cu stomer service to the travelers or passengers. Delta Airlines leads in the airline industry for providing the best airline transportation. The company entered into the industry in the year 2013 by further strengthening its business strategies. It is continuing to improve the performance by executing strategic initiatives. While many of the competitors of the company were focusing on the restructuring efforts or the significant integration, Delta Airline undertook the strategy of advancing its market position across the globe. The innovative business strategies of Delta Airlines (including the re-branding technique) have helped the company in strengthening its position in the world. The acquisition of Northwest Airlines proved to be one of the successful business strategies for the company. This strategy helped the company in reshaping the business goals. In past few years, the company has taken various steps in improving its balance sheet, expanding its operations by getting into gl obal partnership, investment in airlines, such as Virgin Atlantic and finally purchasing oil refinery. It increased its flexibility in these two years in order to reduce its flaws and strengthen the market reputation. However, the launch of the company’s song as a low cost airline followed by its ‘codeshare agreement’ with the Northwest Airlines and the Continental Airlines initiated the declining phase of Delta Airways.  Ã‚

Business Policy and Strategic Management - Essay Example Special alert control is more straightforward to explain. A special alert control is the thorough, and often rapid, reconsideration of the firm’s strategy because of a sudden, unexpected event (Pearce II and Robinson, â€Å"Chapter 13: Strategic Control† Slide 13-10). The economic and financial recession of 2008 greatly affected Starbuck’s key market segments in America and Europe. Surprisingly, the Asian markets were fairly more stable and have continued to grow. Starbucks executives must have been rued that they had not expanded more rapidly globally because they would have been able to balance their portfolio with the Asian outlets if they were many enough. Premise control is designed to check systematically and continuously whether the premises on which the strategy is based are still valid (Pearce II and Robinson, â€Å"Chapter 13: Strategic Control† 13-8). From the lessons learned through the recession, consumer behavior in the Western world is b ound to change, even if only by a small degree. This constituency of â€Å"changing† consumers includes Starbucks’ market segment and therefore the organization will have to redefine who their new target market is, and what their new behaviors are. This may call for, probably, a change of direction in the new products that the company will produce in future.

Illegal immigration Essay Example | Topics and Well Written Essays - 1250 words

Illegal immigration - Essay Example Proponents usually argue for illegal immigration stating various benefits that are received by the US while the others bring forth arguments on how it affects many sectors by adversely shaping the social, economic and political landscape (Ledbetter 46). It is important though to consider why immigrants leave their countries in the first place. There is no doubt that illegal immigrants benefit US in a variety of ways while also having negative effects; however, the issue lies in the net effect where the negatives far outweigh the positives. According to the Commission on Civil Rights (U.S.) there are roughly 12 million illegal immigrants in the United States with Hispanic population taking 80% of total (28). On the other hand the total number of immigrants, legal and otherwise is more than 38 million meaning that the illegal ones hold a third. The same statistics show that by 2060 and at the current rate of immigration, the US will have an alarming total population of 470 million (49). Considering these numbers, it is important to appreciate some facts that form the basis of migration into the United States. Poverty from native countries. It is true that many people who risk travelling to the United States illegally aim at living a better life. The basis for this is poverty and most of these immigrants are from poor families in Mexico, Africa, Asia and Eastern Europe (LeMay 114). The global poverty situation is wanting and many developing countries contribute to mass immigration to the United States. What these people look for mostly are jobs which are in some countries terribly scarce whether one is well educated or not. Profit motive for US companies. Illegal immigrants due to their lack of work permits become quickly absorbed into industries and companies that offer them low wages in return. These industries do so to reduce on remuneration expenditure and offering of benefits like insurance which would otherwise

Article Summaries - Research Paper Example The Board of Regents also wanted to revitalize their education system to fill in the many job openings available in the state which needed certain educational attainments, which in turn could be potential in increasing economic growth in the state. The university plan has just started on July 1, 2012, so the article has no full list of results yet. The Board of Regents of the University System of Ohio made the change in the educational system so that their graduates would become more productive and also to fill the need for professionals in the state of Ohio, both in the business and education sector. Because the plan just started on July 1, 2012, not many results are out yet, but the prevention of high tuition fee increase, faster educational track, saving in school constructions, and inviting investors to generate funding in the universities were already started. The Board of Regents expects that when the changes have all started, there would be an economic growth in the state, more jobs will be filled in, and more students will become productive and better at their careers. The implications of the plan would be that more students can go to universities because the tuition fees are lower, and more will graduate on time and have jobs because the curricula would be more fitted to application in the real world and taught at a faster and more effective rate. The schools can also increase their funding because of additional investors, and their potential of being an economic strength can be released. It is recommended that the results of the changes be checked after one or more years of implementing so that the Board of Regents can see whether the changes made an impact on the labor forces of businesses in Ohio, in the universities’ school standards, and also of the students that graduate from Ohio
