a. Complete the ANOVA table.
b. How many levels were used for each factor? How many treatments were used? How many replications were performed?
c. Find the value of the Sum of Squares for Treatments. Test to determine whether the data provide evidence that the treatment means differ. Use α = .05.
d. Is further testing of the nature of factor effects warranted? If so, test to determine whether the factors interact. Use α = .05. Interpret the result.
