8.11. Refer to Brand preference Problem 6.5. a. Fit regression model (8.22). b. Test whether or not the interaction term can be dropped from the model; use α = .05. State the alternatives, decision rule, and conclusion. 6.5. Brand preference. In a small-scale experimental study of the relation between degree of brand liking (Y) and moisture content (X₁) and sweetness (X₂) of the product, the following results were obtained from the experiment based on a completely randomized design (data are coded): i: X₂: X₁2: Y₁: 1 4 2 64 2 4 4 73 3 4 2 61 14 10 4 95 15 10 2 94 16 10 4 100 8.11.
