AJ Davis Department Store Course Project – Part A MATH533: Applied Managerial Statistic James Butler 03/15/2014 Introduction AJ DAVIS is a department store chain. They have many credit customers and want to find out more information about these customers. Samples of 50 credit customers have been collected. There are five variables in which will be analyzed and deciphered to determine the quality credit customers that AJ DAVIS services. A LOCATION (Rural, Urban, Suburban) Descriptive Statistics: Location Location | | Frequency | Percent | Valid Percent | Cumulative Percent | Urban | 21 | 42.0 | 42.0 | 42 | Rural | 14 | 28.0 | 28.0 | 70 | Suburban | 15 | 30.0 | 30.0 | 100 | Total | 50 | 100.0 | 100.0 | | Reviewing the above information we can see there are three locations in which AJ DAVIS customers are located, rural, urban and suburban.
The p-value associated with it is .157 or approximately 16% this is higher than the acceptable 5% level. Looking at the 95 % confidence interval, the upper bound is .582 which implies that .55 is in the interval, and therefore the hypothesis that p=.55 cannot be rejected in favor of the claim. c) The average (mean) number of calls made per week by salespeople that had no training is less than 145. The number of salespeople without training in the sample of 100 is only 20, so the test statistic used is the T- statistic, which resulted in the conclusion that indeed the speculation is acceptable with associated p-value of .047 which is less than the set probability of .05. With regards the 95% confidence interval, the upper bound is 144.93 which means that 145 is not in the interval that leads us to reject that the hypothesis that the mean is equal to 145 in favor of the claim that it is less
Based on the statistical analysis, we can support the claim that the average (mean) annual income was less than $50,000. We cannot support the claim that the true population proportion of customers who live in an urban area exceeds 40%, the average number of years lived in the current home is less than 13 years and the average credit balance for suburban customers is more than $4,300. a. the average (mean) annual income was less than $50,000, | INCOME($1000) | count | 50 | mean | 43.48 | sample standard deviation | 14.55 | Ho: µ =50000 Ha: µ<50000 The test statistic is Z=(xbar-µ)/(s/√n) =(43480-50000)/(14550.7/√50) =-3.17 The p-value= P(Z<-3.17)= 0.0008 (from standard normal table). Since the p-value is less than 0.05, we reject Ho. So we can conclude that the average (mean) annual income was less than $50,000.
In 2004, China’s GDP was $1938 billion and Denmark’s was $220 billion, but Denmark’s GDP per capita was $40,750 while China’s was $1500. Therefore we are able to depict that Denmark’s living standards are significantly higher than those in China, since the average income for each person in Denmark is much higher. This then tells us that GDP alone is not the appropriate measure of living standards, as it measures the total output of the economy – whereas GDP per capita focuses solely on the income of the citizens as a whole. There are some limitations of using GDP per capita as a measurement for standard of living. For example it is a mean value and does not reflect income distribution, therefore meaning that it doesn’t take into account the fact that there are significantly higher earners than others, as wealth is not distributed equally within an economy.

b) As part of a research project, you need to report the average profitability of the number one corporation in the Fortune 500 for the past 10 years. I would collect the information using a sample, because I will report the average profitability about a population (corporation in the Fortune 500), based on a sample (for the pas 10 years). c) You are looking forward to graduation and your first job as a salesperson for one of five large pharmaceutical corporations. Planning for your interviews, you will need to know about each company’s mission, profitability, products, and markets. The five large pharmaceutical corporations are the entire set of individuals of interest or the measurements.
It is suggested that Nationwide, low-income Americans vote at much lower rate than wealthier citizens, which mirrors the reality that more than three quarters of all citizens in households with incomes over $75,000 are registered to vote but less than half of citizens in households earning under 15,000 are registered ( Fleishmann, 2004). There is an important lesson learned in understanding the correlation that exists between non-voting members of society and lower economic and social
When comparing the financial results of the companies, it can be said that The Gap Company is the largest competitor among others for Inditex. The Gap has the highest net operating revenues which is around five times Inditex numbers. Therefore, I think The Gap is the most interesting international competitor to compare. Despite the fact that it has the highest revenue, The Gap had a massive decline in its stock prices in 2001 and as a result the company incurred a net loss of 9 million euros. On the other hand, Inditex has achieved net income of 340 million euros in 2001 with relatively such small revenue.
| 05 | 06 | 07 | EBITDA Margin | 8.6% | 15.6% | 9.7% | 5. What method to valuate inventories (FIFO, average weighting cost, LIFO…) has been used? The increase in purchases is of 44% and 22% in 06 and 07 respectively. As to the sales the increase was of 34% and 18%. We can conclude that they use FIFO because the inventory amount increases through 06 in 65% and then decreases in 07 by -13%.
When the 2000 statistics was gathered, the entire total population was 48, 754 inhabitants. Based on City Facts (2010) the average family revenue in 2008 was $67,243, while the average unattached house was worth $557,392, furthermore, the living costs index was 140.3. Rowland Heights accounts that 6.8% of its residents have earnings of 51%, lower than the average resident, and a joblessness rate of 6.5% (City Data, 2010). Roughly 43.5% of residents are females, 56.5% males, and of that 83.1% have a minimum of a high school education. About 34.4% possess a bachelor’s level education, and 11.6% have a professional or graduate education (City Data, 2010).
