1) A large software company gives job applicants a test ofprogramming ability and the
mean for that test has been 160 in the past. Twenty-five jobapplicants are randomly
selected from one large university and they produce a mean scoreand standard
deviation of 183 and 12, respectively. Use a 0.05 level ofsignificance to test the claim that
this sample comes from a population with a mean score greater than160. Use the
P-value method of testing hypotheses.
