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 = 25. Assume the standard deviation is = 63 and let u 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 Ho=0 versus H₁ μ>0. Compute the P-value. 2.6022 0.0046 0.0012 0.0023
