After reading Chapters 14 (Sampling), 15 (Analysis and Presentation of Data) and, 16 (Exploring, displaying and examining data), answer the questions below.

  • 1. Open the attached case “Campbell-Ewald Pumps Awareness into the American Heart Association case”. Then, once you have read the case, answer questions 2 and 3. Answer the questions in APA style.
  • 2. Assume the following:

2.1. A lakefront resort is planning for its summer busy season. It wishes to estimate with 95% confidence the average number of nights each guest will stay for a consecutive visit. Using a sample of guests who stayed last year, the average number of nights per guest is calculated at 5 nights. The standard deviation of the sample is 1.5 nights. The size of the sample used is 120 guests and the resort desires a precision of plus or minus .5 nights. What is the standard error of the mean in the lakefront resort example? Within what range below can the resort expect with 95% confidence for the true population means to fall? Show the calculation; otherwise, the answer will not be accepted.

2.2. A local restaurant is planning a study on the demand for meals over holiday weekends. In calculating the desired sample size for the study, the restaurant’s researcher decides to use a rule-of-thumb calculation for estimating the population dispersion. If the range of meals in the study is 0 to 30, what standard deviation does the rule-of-thumb method produce? Show the calculation; otherwise, the answer will not be accepted.

2.3. A microbrewery plans to conduct a study on beer consumption among men between the ages of 29 and 45. A pilot test indicated that men in this age category consume an average of 6 beers per week with a standard deviation of 2.3. If the microbrewery seeks a 95% confidence level and a precision of .5 beers, what size sample should be used in the study?
Show the calculation; otherwise, the answer will not be accepted.

3. Open the attached case “Mastering Teaching Leadership case”. This exercise is a data analysis assignment. Then, once you have read the case and analyzed the survey’s results, follow the steps shown below:
