Models with indicator variables. Suppose that x is an indicator variable with the value 0 for Group A and 1 for Group B. The following equations describe relationships between the value of y and membership in Group A or B. For each equation, give the value of the mean response y for Group A and for Group B.

(a) y 5 10 1 5x.

(b) y 5 5 1 10x.

(c) y 5 5 1 100x.
