Answer true or false to each of the following statements and explain your answers. a. The number of indicator variables required to represent the possible values of a qualitative predictor variable is one more than the number of possible values. b. If we take the regression equation relating the response variable y to a quantitative predictor variable x1 and indicator variables x2 and x3 to be y = β0 + β1x1 + β2x2 + β3x3, then we are assuming there is no interaction between x1 and the qualitative variable represented by x2 and x3. c. A cross-product term in a regression equation is often referred to as an interaction term.

The director of marketing at Vanguard Corporation believes that sales of the company's Bright Side laundry detergent (S) are related to Vanguard's own advertising expenditure (A), as well as the combined advertising expenditures of its three biggest rival detergent (R). The marketing director collects 36 weekly observations on S, A and R to estimate the following multiple regression equation: S = a + bA + cR .where, S, A, and R are measured in dollars per week. Vanguard's marketing director is comfortable using parameter estimates that are statistically significant at the 10% level or better.DEPENDENT VARIABLE: S R-SQUARE F-RATIO P-VALUE ON FOBSERVATIONS: 36 0.2247 4.781 0.0150VARIABLE PARAMETER STANDARD T-RATIO P-VALUE ESTIMATE ERRORINTERCEPT 175086.0 63821.0 2.74 0.0098A 0.8550 0.3250…

Answer true or false to each of the following statements and explain your answers. a. In a regression equation involving a quantitative predictor variable x1 and a single indicator variable x2, the t-test of the utility of the interaction term is a test that the regression lines are parallel for the two values of the qualitative variable. b. If the regression lines relating the response variable y to a quantitative predictor variable x1 have the same y-intercept for each category of a qualitative predictor variable, then there is no interaction between the two predictor variables.
