Panlnc. Par, Inc.. is a major manufacturer of golf equipment. Management believes that Par's market share could be increased with the introduction of a cut-resistant, longer-lasting golf ball. Therefore, the research group at Par has been investigating a new golf ball coating designed to resist cuts and provide a more durable ball. The tests with the coating have been promising. One of the researchers voiced concern about the effect of the new coating on driving distances. Par would like the new cut-resistant ball to offer driving 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 testing was performed with a mechanical hitting machine so that any difference between the mean distances for the two models could be attributed to a difference in the two models. The results of the tests. with distances measured to the nearest yard, follow.

Use appropriate descriptive statistics to summarize the driving distance data for each model. What similarities or differences do you observe from the sample data? 2. Use the tests of hypothesis procedure to comment on any difference between the population means for the two methods. Discuss your findings. 3. Compute the standard deviation and variance for each model. Conduct a hypothesis test about the equality of population variances for the two models. Discuss your findings. What conclusion can you reach about any difference between the two models? Can you suggest other data or testing that might be desirable before making a final decision on the golf ball to be used in the future? .0"
