Base on below GMAT score answer questions a. GMAT Scores 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 the Graduate Management Admission Test (GMAT) scores of those who are accepted into the school. A random sample of six students in each school produced the following GMAT scores. Assume that the data are normally distributed with equal variances for each school. School 1 650 620 630 580 710 690 GMAT Scores School 2 510 550 700 630 600 650 School 3 590 510 520 500 490 530 Use this given to answer the next three questions. Calculate the mean square for treatments: O a. 27,756 O b. 26,756 O c. 25,756 d. 23,756 b. Using the GMAT example, calculate now the mean square for error (MSE): a. 2,760 O b. 2,860 O c. 2,660 O d. 2,960 C. Using the GMAT exercise, calculate the ANOVA F-statistic and interpret the test at 5% significance level O a. The F-statistic is 8.61; we do not reject HO and conclude that GMAT means are equal. b. The F-statistic is 8.61; we reject HO and conclude that at least 2 GMAT means are different. Oc. The F-statistic is 8.61; we reject HO and conclude that GMAT means are equal Od. The F-statistic is 8.61; we do not reject HO and conclude that at least 2 GMAT means are different.
