F9 c. Translate these questions into contrasts: Control Rolling Microwave Microwave Rolling V1 d. Are these contrasts orthogonal? Justify your answer. e. For each of these contrasts, compute the sum of squares explained separately (SSy, and SS42). Also compute the sum of squares for the authors' contrasts overall (SSy, + SS42). f. What is the proportion of the experimental variance explained by the authors' contrasts (hypotheses) overall? g. What is the proportion of the total variance explained by the authors' contrasts (hypotheses) overall? The authors wanted to perform a post-hoc pairwise comparison of the means of all levels of the independent variable ing a Tukey Test. Find the critical value they should use at a = 0.01
