One of the researchers voiced concern about the burden of the new coating on driveway distances. Par would like the new cut-resistant ball to offer madcap distances comparable to those of the current-model golf ball.To compare the driving distances for the two balls, 40 balls of both the new and current models were subjected to distance tests. The interrogatory was performed with a mechanical hitting machine so that any remnant between the mean distanced for the two models could be attributed to a difference in the two models. The results of the tests, with distances measured t o the nearest yard, follow. These info are available on the excel file Golf. Managerial Report 1. Formulate and portray the rationale for the possibility test that par could use to compare the driving distances of the current and new golf balls. . Analyze the data to provide the hypothesis interrogation conclusion. What is the p-value for the test? What is your recommendation for Par, Inc.? 3. Provide descriptive statistical summaries of the data for severally model. 4. What is the 95% confidence interval for the population mean of each model, and what is the 95% CI for the difference between the actor of the two populations? 5. Do you see a need for the larger sample sizes and more testing with the golf balls? talk of.

Any difference between topical anesthetic and foreign tuition costs. b. Any difference between mean kickoff salaries for schools requiring and not requiring work experience. c.
