A sample of 43 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 i=9. Assume the standard deviation is a= 42 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 Hui}: =0 versus H1'#}0. Using technology, compute the P-value. O 0019996526 0 0079986104 0 1.405165393 0 0039993052
