Using four methods to teach ANOVA, do these four samples differ enough from each other to reject the null hypothesis that type of instruction has no effect on mean test performance?Method to teach ANOVA Mean SD Nmethod 1 (single teacher) 4.85 0.360 34method 2 (co-teachers) 4.61 0.715 31method 3 (computer) 4.61 0.688 36method 4 (lab) 4.38 0.793 32Since we are comparing more than 2 groups, we will use ANOVA to test whether the data provide evidence that test score is related to teaching method. Let μ1, μ2, μ3, and μ4 be the mean test scores for teaching using methods 1, 2, 3, and 4 respectively. Which of the following are the appropriate hypotheses in this case?A. H0: µ1 = µ2 = µ3= µ4Ha: µ1, µ2, µ3, µ4 are not all equalB. H0: µ1 − µ2 < 0Ha: µ1 − µ2 = 0C. H0: µ1 = µ2 = µ3= µ4Ha: µ1 ≠ µ2 ≠ µ3≠ µ4D. H0: µ1 ≠ µ2 ≠ µ3 ≠ µ4Ha: µ1 = µ2 = µ3 = µ4
