12.3 Random sampling of individuals with sity found the following grade point averages (GPAS) for the four groups: Major A: GPA = 3.23 (N = 178) Major B: GPA = 2.76 (N = 64) Major C: GPA 2.18 (N= 99) Major D: GPA = 3.54 (N = 121) %3D If the between-group variance is 5.7 and the within-group variance is 1.5, are the GPAS different for the four majors? Use a significance level of 0.01, and write out all of the steps of a test of statistical significance, violations of as imntions
