Par, Inc., is a major manufacturer of golf equipment. Management believes that Pars

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. Theresults

of the tests, with distances measured to the nearest yard, follow. These data are available

on the website that accompanies the text.
