The partially completed ANOVA for a 3 * 4 factorial experiment with two replications is shown below.

a. Complete the ANOVA table.

b. Which sums of squares are combined to find the Sum of Squares for Treatments? Do the data provide sufficient evidence to indicate that the treatment means differ? Use α = .05.

c. Does the result of the test in part b warrant further testing? Explain.

d. What is meant by factor interaction, and what is the practical implication if it exists?

e. Test to determine whether these factors interact to affect the response mean. Use α = .05 and interpret the result.
