- Analyze the data to provide the hypothesis testing conclusion. What is the p-value for your test? What is your recommendation for Par, Inc.?
- Provide descriptive statistical summaries of the data for each model.
- Explain what the 95% confidence interval is for the population mean driving distance of each model, and explain what the 95% confidence interval is for the difference between the means of the two populations.
- Discuss whether you see a need for larger sample sizes and more testing with the golf balls.
