Both the quality of management and the reputation of the company were rated on an excellent, good, and fair categorical scale. Assume the sample data for 200 respondents below applies to this study.### Data Summary**Excel File:** [data12-13.xlsx]| Quality of Management / Reputation of Company | Excellent | Good | Fair ||-----------------------------------------------|-----------|------|------|| Excellent | 40 | 25 | 5 || Good | 35 | 35 | 10 || Fair | 25 | 10 | 15 |### Analysis Tasks**a.** Use $\alpha = 0.05$ level of significance and test for independence of the quality of management and the reputation of the company.- Compute the value of the $\chi^2$ test statistic (to 2 decimals). Do not round intermediate calculations.- Use Table 3 of Appendix B to find the $p$-value.- Indicate your conclusion by selecting whether the rating for the quality of management is independent or dependent on the rating for the reputation of the company.**b.** If there is a dependence or association between the two ratings, discuss and use probabilities to justify your answer.- Explain which ratings combination is most probable based on the data (e.g., both excellent, both good, etc.).### Instructions1.

(a) TV stations use ratings to decide which shows to keep or cancel. Therefore, the A. C. Nielsen Company collects data on the TV viewing habits of Americans and publishes the information in Nielsen Report on Television. Suppose that you want to use a paired sample to decide whether the mean viewing times of married men and married women differ: 1. Identify the variable. 2. Identify the two populations. 3. Identify the pairs. 4. Identify the paired-difference variable.
Bank of America's Consumer Spending Survey collected data on annual credit card charges in seven different categories of expenditures: transportation, groceries, dining out, household expenses, home furnishings, apparel, and entertainment. Using data from a sample of 42 credit card accounts, assume that each account was used to identify the annual credit card charges for groceries (population 1) and the annual credit card charges for dining out (population 2). Using the difference data, the sample mean difference was d = $850, and the sample standard deviation was Sd = $1,123. a.
