Recall: A research laboratory was developing a new compound for allergy relief, and was manipulating the dosage of two ingredients. Information on the dataset follows: Column 1: Relief: The number of hours of relief. Column 2: 003911: The dosage of the rst ingredient, with values of Low, Med, High. Consider this to be factor A. Column 3: 00398: The dosage of the second ingredient, with values of Low, Med, High. Consider this to be factor B. You may assume that ii = 1 is low, 3' = 2 is medium, and 2' = 3 is high, and similarly for j. The following table gives the group means, and the sample sizes (in parentheses): Further, consider the appropriate model to use the model with Low 2.43 (4) 4.60 (4) 4.53 (4) 3.33 (12) Med 5.45 (4) 3.93 (4) 9.12 (4) 7.33 (12) High 5.97 (4) 10.23 (4) 13.25 (4) 9.33 (12) B 4.63 (12) 7.93 (12) 3.93 (12) 7.13 (35) interactions, where SSE = 1.63
