A sample 0139 students enroll in a program that claims to improve scores on the quantitative reasoning portion of the Graduate Record Examination (GRE). The participants take a mock GRE test before the program begins and again at the end to measure their improvement. The mean number of points improved was 3_c= 12. Assume the standard deviation is a=40 and let ,u be the population mean number of points improved. To determine whether the program is effective, a test is made of the hypotheses How =0 versus H131: > 0, Compute the P-value. Q 0.0076 Q 00153 O 0.0305 0 1.8735
