Forty-nine 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 x = 5. Assume the standard deviation is o = 49 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: μ = 0 versus H₁:μ> 0. Do you reject H at the a= 0.05 level?
