CHAPTER 6 BUSINESS APPLICATIONS OF SAMPLING CASE STUDY Marymount wants to design, deliver, and analyze a patron satisfaction study regarding the quality of its campus shuttle service, especially between main campus and Ballston. This survey is specific towards the shuttle service, and not “generic.” Marymount wants the survey to have at least the following in its structure. a. Distinguish survey results between faculty, staff, and student patrons. b. Have a large enough sample size to have a small margin of error. Not all patrons who will get the survey will respond, so the distribution needs to be three times larger than the sample expected of completed surveys. c. Be able to distribute the surveys within one week. d. Have each survey question answered on a Likert Scale from 1 (very dissatisfied) to 5 (very satisfied). e. Be able to analyze each question and its margin of error for responses. Design the process for building this satisfaction survey. CASE STUDIES: CHAPTER 6 BUSINESS APPLICATIONS OF SAMPLING CASE STUDY GRADING RUBRIC Student name: 1. Describe the sampling process. Is the sampling process statistically sound for this study. 2 pts. 2. Discuss the minimum sample size to collect. 2 pts. 3. Determine how you intend to distribute the surveys. 2 pts. 4. Provide a sample question to demonstrate how you would design the questions for the survey. Explain why you designed it this way. 2 pts. 5. How will you determine the average response and margin of error for each question. Be specific, and include a hypothetical example using hypothetical numbers to illustrate. 3 pts. CHAPTER 7 HYPOTHESIS TESTING CASE STUDY Hypothesis testing can be important when developing performance standards for your subordinates. Each of you will be a manager, and each of you will therefore need to develop performance standards which will clearly allow you (and your subordinate) to agree as to whether or not the subordinate met your requirement. You do not want to end a rating period with disagreement on the subordinate’s performance, and you do not want to lose a grievance to upper management should the subordinate appeal your performance rating. (A subordinate certainly has every right to appeal, but you should never lose an appeal!) Suppose that you are manager of a restaurant, and need to develop a series of performance standards for each member of your staff. The restaurant is a full-service restaurant, with seated customers, menus, a hostess to meet customers and seat customers, etc. Examples might include Joe Theismann’s, an IHOP, an Outback Steakhouse, etc. For this case study, develop one measurable, numeric performance standard for a member of the wait staff. Then show how you could take a random sample of 30 readings of the performance and develop a hypothesis test using the t statistical method to determine, at 95% confidence, if the performance standard was met. List 30 notional (hypothetical) “readings” and calculate a corresponding notional t-test to show how your subordinate hypothetically performed. You will need to calculate the sample mean, sample standard deviation, use the t table in the back of the book, etc., to complete the analytics. You must use Excel to log your data and perform many or all of your analytics, and you will submit your Excel file (and any other files you may find convenient to submit such as photos of your calculations if done long-hand). This may be a one-tail test. At the 95% confidence level, using the notional data, can you conclude that the subordinate is meeting your standard. CASE STUDIES: CHAPTER 7 HYPOTHESIS TESTING CASE STUDY GRADING RUBRIC Student name: a. State the null hypothesis. 1 pt. b. State the alternative hypothesis. 1 pt. c. State the significance level. 1 pt. d. Perform the calculations. 3 pts. e. What is your conclusion. Discuss why or why not you would statistically accept the null hypothesis, with the understanding that you could be wrong 5% of the time. Also discuss if this is a total fair test of if other circumstances need to be considered before drawing any final conclusions – the numbers do not always tell the entire story. 3 pts. ...

CHAPTER 7 HYPOTHESIS TESTING CASE STUDY
Hypothesis testing can be important when developing performance standards for your subordinates.
Each of you will be a manager, and each of you will therefore need to develop performance
standards which will clearly allow you (and your subordinate) to agree as to whether or not the
subordinate met your requirement. You do not want to end a rating period with disagreement on
the subordinate’s performance, and you do not want to lose a grievance to upper management
should the subordinate appeal your performance rating. (A subordinate certainly has every right to
appeal, but you should never lose an appeal!)
Suppose that you are manager of a restaurant, and need to develop a series of performance
standards for each member of your staff. The restaurant is a full-service restaurant, with seated
customers, menus, a hostess to meet customers and seat customers, etc. Examples might include
Joe Theismann’s, an IHOP, an Outback Steakhouse, etc.
