: Suppose that we want to test the hypothesis Ho : M1 = (2 = u3 vs H1 : u, # uj for at least one pair (1, J) based on three independent samples using ANOVA. The analysis requires that the residuals all have the same variance. Which of the following methods could be used to check this assumption? (1) Use the ANOVA overall F-test. (ii) Construct a normal probability plot of the residuals and see if the points fall close to a straight line. (iii) Construct a residuals vs fitted values plot and look for a random scattering of points. (A) (ii) only (B) (i) only (C) none of them (D) (iii) only (E) (ii) and (iii) only (F) all of them (G) (i) and (iii) only (H) (i) and (ii) only 7: Select v
