Forty-three members of a bowling league sign up for a program that claims to improve bowling scores. The participants bowl a set of five games before the program begins and a set of five games again at
The end to measure their improvement. The mean number of points improved (over the set of five games) was $\bar { x } = 8$ . Assume the standard deviation is $\sigma = 62$ and let $\mu$ be the population mean number of points improved for the set of five games. To determine whether the program is effective, a test is made of the hypotheses $H _ { 0 } : \mu = 0$ versus $H _ { 1 } : \mu > 0$ . Using technology, compute the P-value.
