Consider the following data from a two-factor experiment:

Factor A Factor B Level 1 Level 2 Level 3 Level 1 43 25 37 49 26 45 Level 2 50 27 46 53 31 48

a. Determine if there is interaction between Factor A and Factor B. Use the p-value approach and a significance level of 0.05.

b. Does the average response vary among the levels of Factor A? Use the test-statistic approach and a significance level of 0.05.

c. Determine if there are differences in the average response between the levels of Factor B. Use the p-value approach and a significance level of 0.05.
