22. A recent college graduate is in the process of deciding which one of three graduate the Graduate Management Admission Test (GMAT) scores of those who are accepted GMAT scores. Assume that the data are normally distributed. GMAT Scores School 2 School 1 650 620 630 580 710 690 505 550 700 630 600 650 School 3 590 510 520 500 490 530 a) Set up the ANOVA Table. Use a -0.10 to determine the critical value. b) Can he infer at the 10% significance level that the GMAT scores differ among the three schools? c) Use Fisher's LSD method with a 0.05 to determine which population means differ. d) Use Tukey's method with a -0.05 to determine which population means differ.

8:14 1 Done ED ← 22. A recent college graduate is in the process of deciding which one of three graduate schools he should apply to. He decides to judge the quality of the schools on the basis of into the school. A random sample of six students in each school produced the following the Graduate Management Admission Test (GMAT) scores of those who are accepted GMAT scores. Assume that the data are normally distributed. School I 650 620 630 580 710 690 GMAT Scores School 2 505 550 700 630 8 of 26 600 650 School 3 590 510 520 500 490 530 a) Set up the ANOVA Table. Use a -0,10 to determine the critical value. b) Can he infer at the 10% significance level that the GMAT scores differ among the three schools? C) Use Fisher's LSD method with a = 0.05 to determine which population means differ. d) Use Tukey's method with a=0.05 to determine which population means differ.
