A lecturer in a university wants to investigate the differences in students' marks with the different majors from School A, School B, School C and School D for MSG 162 subject. It was thought that students with four different majors might result in different grades for MSG 162. The lecturer examined exam scores for a sample of four students each from the school that participated in the MSG 162 class. The following are the MSG 162 exam results for the students: School A B C D Marks 85 67 88 77 79 75 79 56 76 72 85 60 83 80 82 70 Assume that all assumptions to perform an ANOVA test are satisfied. a) Test the hypothesis that there is no difference between exam scores of students from four schools at the significance level, a = 0.05. Interpret the results of the hypothesis testing. b) Determine the level of significance (p-value) of the test results.
