Chapter 8, Problem 12E(choose chapter or problem)
To test whether a golf ball of brand A can be hit a greater distance off the tee than a golf ball of brand B, each of 17 golfers hit a ball of each brand, 8 hitting ball A before ball B and 9 hitting ball B before ball A. The results in yards are as follows:
Assume that the differences of the paired A distance and B distance are approximately normally distributed, and test the null hypothesis \(H_{0}: \mu_{D}=0\) against the alternative hypothesis \(H_{1}: \mu_{D}>0\), using a paired \(t\) test with the 17 differences. Let \(\alpha=0.05)\).
