Question:

A two-factor analysis of variance experiment was performed with a  3, b  4, and r  20. The following sums of squares were computed:

SS(Total)  42,450 SS(A)  1,560 SS(B)  2,880 SS(AB)  7,605

a. Determine the one-way ANOVA table.

b. Test at the 1% significance level to determine whether differences exist between the 12 treatments.

c. Conduct whatever test you deem necessary at the 1% significance level to determine whether there are differences between the levels of factor A, the levels of factor B, or interaction between factors A and B.
