Formulate and present the rationale for a hypothesis test that Par could use to compare the driving distances of the current and new golf balls.
2. The CEO tells you (in contrast to what Bill said) that he would like to sell the new ball unless there is overwhelming evidence that the cut-resistant ball is slower than the old ball so you should frame your hypothesis accordingly. Hint: you are more willing to make a Type II error (see pp. 408-410): Analyze the data to provide the hypothesis testing conclusion and statements (at .05). Use one of the formats hypothesis formats or the appropriate format from your textbook (can use H1 and H2).

3. Provide the following descriptive summaries of the data for each model: ONLY the means and variances and the z values.

4. What is the 95% confidence interval for the difference between the means of the two populations?

5. Do you see a need for larger sample sizes and more testing with the golf balls? Discuss.
