The experimenter finds that factors D&E actually has no impact on the test response and decide to drop them from further analysis. Tests using single replicate per combination of test conditions are given below. Using the data in the table below, draw the interaction plot of factors A and C (5%). Do factors A and C have significant interaction effect? Explain.
