...Wal-Mart began selling shares as a publicly-held company and its stock experienced its first 100% split, at a market price of $47. By 1990, Wal-Mart had become the nation’s No. 1 retailer and by the end of the decade, the largest private employer in the world, with 1.14 million associates. Soon after, H. Lee Scott Jr. was appointed as the third CEO of Wal-Mart Stores Inc. In 2005, Scott introduced the company’s new commitment to bring environmental sustainability into its business and passed his success onto his replacement as president and CEO, Mike Duke, on February 1, 2009. Today, Wal-Mart has 7,800 stores and club locations in 14 different markets, employing more than 2 million associates, and serving more than 176 million customers a year. Wal-Mart is a public corporation that runs a chain of large department stores. Three business subsidiaries comprise Wal-Mart’s operations: Wal-Mart Stores, Sam’s Club, and Wal-Mart International. The nine retail formats of the company include “supercenters, food and drug stores, general merchandise stores, bodegas (small markets), cash and carry stores, membership warehouse clubs, apparel stores, soft discount stores and restaurants” (p. 17). Studies show that the customer base for discount retailers has been growing since early 2007, but bargain shoppers have especially flocked to discount retailers since the recession hit. Last year's increase in gasoline prices has also benefited retailers such as Wal-Mart who are known for their one-stop...

...what they can afford to buy; or even what they think they can afford to buy. With the economy being where it is right now, most people are also looking at the benefits that the car may offer, such as having low gas mileage. The hypothesis test will determine the percentage of imported cars sold at the dealership. In the conclusion, the hypothesis will either be accepted or rejected after determining the actual probability. The level of significance to be used for this calculation is .05 or 95% confidence level. Numerical Hypothesis X1: Selling price in dollars X2: Selling price in thousands of dollars X3: Age of buyer X4: 0=Domestic, 1=Imported 80 Autos Sold Ho- p= .5 (The true hypothesis should be that out of the 80 cars that were sold, 40 of them should be imported cars.) Ha- p < .5 or p > .5 (The actual statement states that out of the 80 cars sold, the number of imported cars will either be less than 40 or more than 40.) Verbal Hypothesis The percentage of imported cars sold at the Whitner Autoplex dealership should be 50%. Since the dealership carries both imported cars and domestic cars, the probability of the number of cars sold should be even, 50% imported -50% domestic. In the conclusion this hypothesis will be accepted or rejected. We tested the Autoplex data to determine the 90% and 95% chance that the cars sold on the lot are...

...The Hedonist Perspective - Ursa Minor Beta Eroticon To live the ‘good life’- meaning to live a life of satisfaction in our everyday lives, one must compel to live and practice a life of pleasure. Living a life of pleasure refers to the actions, and thoughts, one must take in order for that fulfillment to be reached. The attainment of pleasure depends on the individual’s perception of what it means to feel pleasured. For example, one individual may be pleasured by the action of collecting comic books, while another individual may be pleasured by tearing apart comic books. In this case, it is to do whatever one must feel comfortable doing in order to reach the final end. The ultimate end is pleasure. The best form of pleasure to be practiced is to be peaceful, and negotiable to whatever the action the individual may take on. This practice is beneficial to move further away from negative forms of pain, and instead enhance all sectors of life to the best form it can be. Nature has placed species all around the universe under two sectors of governance – Pain and Pleasure. Pain inflicts negative unpleasant experiences and feelings of guilt, remorse, aches, and discomfort. Pleasure inflicts delight, satisfaction, enjoyment, and elation. Virtue allows us to be free from forms of pain, and disturbing events. Practising the pleasure sector governs our perception of life in the most positive format. We are able to distinguish our morals by what gives us the most pleasure in what we do...

...variables such as marital, eservice, plusservice and totalservice we use the log-rank test of equality across strata which is a non-parametric test. For the continuous variables such as age, address, income, education, employment, and reside we use a univariate Cox proportional hazard regression which is a semi-parametric model. Univariate analysis We consider the Chi-squared test for age, address, income, education, and employ. All the variables have p-values of 0.0000 thus age, address, income, education, and employ are the potential candidate for the final model since the p-value is less than our cut-off value of 0.2. But we get different result in case of reside. We consider the Chi-squared test for reside which has a p-value of 0.5413 thus reside is not a potential candidate for the final model since the p-value is more than our cut-off value of 0.2. The log-rank test of equality across strata for the predictor marital has a p-value of 0.0136, thus marital will be included as a potential candidate for the final model because this p-value is still less than our cut-off of 0.2. From the graph (exhibit 1), we see that the survival function for each group of married or unmarried people are not perfectly parallel but separate except at the very beginning and at the very end.

We are full of lust, sensuality and emotions and we call it love 4. we want to have wonderful marriages, but by the time we are 25years we've spent almost ten years in relationships already. Sometimes we may have had more boy lovers and girl lovers than even our parents. 5. Sexual activities are now part of our relationships calling it romance 6. we want to be rich in life, meanwhile we spent all our finances on the latest ipads, iphone, galaxies, htcs, laptops, cameras etc which in many cases we use less than 30% of their functions 7. We do not pay our tithes and offerings claiming we are students 8. We say we are christian women but dress like hollywood stars and we call it fashion 9. We love pleasures rather than God 10.

...A high school principal wanted to know if the racial makeup of her teachers mirrored that of the student body. The student body broke down into 47% White, 28% Latino, 15% African American, and 10% other. Of the 65 teachers, 42 were White, 4 were Latino, 15 were African American, and 4 were Other. Do these results suggest that the racial makeup of the faculty members is different from that of the students? (Use the .05 significance level.) Use the five steps of hypothesis testing and explain your findings. Since the teachers are given in numbers and the students in percentage therefore we will write both in percentage. | |White |Latino |Af.American |Other |Total | |% of students |47 |28 |15 |10 |100 | |% of faculty |64.6 |6.15 |23.1 |6.15 |100 | |Total |111.6 |34.15 |38.1 |16.15 |200 | Step1- H0: The racial makeup of faculty members is independent of that of the students.

This is only to be expected because more skills a person has, more confident she is and therefore less prone to being anxious. (c) R = -0.9800 and R^2 = 0.9603 We see that R = -0.98, which is close to -1, indicating a high degree of negative correlation between dexterity and anxiety. R^2 = 0.9603, which implies that 96.03% of the variation in anxiety can be explained by the variation in dexterity.

... the r value is not significant since it’s associated p-value = 0.424 > 0.05 which is the level of significance. 2.Consider r = 1.00 and r = −1.00. Which r value is stronger? Provide a rationale for your answer. Answer: The r values have similar perfect strength. The positive r value shows a positive relationship between the variables, which means as one variable increases so does the other. The negative r values shows a negative relationship, which means as one variable increases the other decreases. 3.Describe the direction of the relationship between the Hamstring strength index 60°/s and the Shuttle run test. Answer: The r value in this case is negative. So as Hamstring strength index 60°/s increases the Shuttle run test decreases, and vice versa. 4.Without using numbers, describe the relationship between the Hamstring strength index 120°/s and the Triple hop index. Answer:There exists a moderate positive relationship between Hamstring strength index 120°/s and the Triple hop index. This means as Hamstring strength index 120°/sincreases, Triple hop index increases. Likewise as Hamstring strength index 120°/s decreases, Triple hop index decreases. 5.Which variable has the weakest relationship with the Quadriceps strength index 120°/s? Provide a rationale for your answer. Answer:The Shuttle run test has the weakest relationship with Quadriceps strength index120°/s. That is because the absolute value of the r value is less than all the others, and the p value is greater than all others...

...1 1 Mount Everest-1996 2 2 Executive Summary Background The case study describes a team ascending Mount Everest led by Scott Fischer and Rob Hall. The primary concept behind the case study is to distinguish qualities in the team’s plan, action, and most importantly leadership. The clients and the leaders in the report show lack of readiness to ascend the mountain. Fischer along with Hall led many people to their deaths because of bad leadership skills. The report outlines how the two leaders failed to communicate with their team. The expedition team needed a better action plan with clear and concise steps to follow in order to keep everyone alive. The breakdown and analysis of the case is reported here. Results Scott Fischer and Rob Hall were not prepared to be leaders. Their skills were lacking and they were only doing things for themselves. Fischer and Hall were clearly acting in the pre-conventional stage of development. They did not value any objections to ideas or procedures. The two leaders acted in a high power distance setting, neither were comfortable allowing inexperienced individuals have a voice. They failed to keep in mind they were running a business. Their actions were the primary reason many climbers lost their lives. The report outlines the communication errors and expresses potential solutions that could have saved lives. Conclusion Communication is a primary factor in the business environment. Leaders need to communicate their business...

...Explain the difference between a left-tailed, two-tailed, and right-tailed test. When would you choose a two-tailed test? How might you tell the direction of the test by looking at a pair of hypothesis? How might you tell which direction (or no direction) to make the hypothesis by looking at the problem statement (research question)? The direction of the test is indicated by the alternate Hypotheses H1. < indicates a left tailed test and > indicates a right tailed test. One would choose a two tailed test when the direction of < or > does not matter to the researcher. Two tailed tests are indicated by =. One would also choose a two tailed test if the rejection of the two tailed test guarantees a rejection of the left or right tailed test. I think one can tell which direction the hypothesis should be by the way the research question is worded. Certain words can mean less than or greater than;: or equal to or not equal to; or greater than or equal to some number. One just needs to read the hypothesis carefully to make sure he or she is conducting the test in the correct direction or the test will be done wrong. An example of this would be where the average means of monthly wages for a population area is $1,800 and someone questions this saying they believe it is higher for the particular area. So the hypothesis for this particular scenario would be written out as: H0 : µ > 1,800 H1 : µ ≤ 1,800 Please try to respond to this question by at least...

...After I read Mill’s notion of higher and lower pleasures, I changed the view of my opinion about higher and lower pleasures. Before that, I thought we just need happiness, and then it will be ok. I never think about what kind of pleasures are higher or lower. Through Mill’s view, it’s really difficult to define higher and lower pleasure. But at least, Mill equates happiness with pleasure, and not all pleasures have equal value; higher pleasures of the mind are better than lower pleasures of the body. For human beings, first thing is to seek the most and best food, drink, sleep, sex and so on. This can satisfy people’s lower pleasure. However, people also need higher pleasures. So what are higher pleasures? It mostly focuses on spiritual happiness. Of course, after people’s lower pleasures been satisfied, then people can started to seek higher pleasures. Try to think about it, if people cannot feed themselves, who will try to learn the science. So, reading a good book, seeing a good play or other edifying pleasures would be far superior and would supersede food, drink, sleep, sex etc. When people who are tolerably fortunate in their outward lot find life unhappy, it usually is because they lack altruism or are deficient in mental cultivation. Those who cherish a fellow-feeling for others will always retain a pleasurable interest in life; and a cultivated mind finds inexhaustible interest in all that surrounds it--nature, art, poetry, history, the past, present and future of mankind...
