Following is a partially completed ANOVA table for a 3 * 4 factorial experiment with two replications:

a. Complete the ANOVA table.

b. Which sums of squares are combined to find the sum of squares for treatment? Do the data provide sufficient evidence to indicate that the treatment means differ?
Use a = .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 a = .05, and interpret the result.

f. Does the result of the interaction test warrant further testing? Explain.
