In a two-way ANOVA, the P-value for interactions is P = 0.45, and the P-values for the main effects are P = 0.023 for the row factor and P = 0.34 for the column factor.

a. Can you reject the hypothesis of no interactions? Explain.

b. Is it appropriate to interpret the main effect of the row factor? If so, state whether there are differences in the mean response among different levels of the row factor, using the α = 0.05 level of significance. If not, explain why not.

c. Is it appropriate to interpret the main effect of the column factor? If so, state whether there are differences in the mean response among different levels of the column factor, using the α = 0.05 level of significance. If not, explain why not.
