Compensation. To encourage performance, loyalty, and continuing education, the human resources department at a large company wants to develop a regression-based compensation model (Comp in $ per year) for midlevel managers based on three variables: (1) business-unit profitability (Profit in $1000s per year), (2) years with the company (Years), and (3) whether or not the manager has a graduate degree (Grad equals 1 if graduate degree, 0 otherwise). The accompanying table shows a portion of data collected for 36 managers
a. Estimate the following model for compensation: Comp = 0 + 1Profit + 2Years + 3Grad + 4(Profit Grad) + 5(Years Grad) + .
b. At the 5% significance level, is the overall regression model significant?
c. Which predictor variables and interaction terms are significant at = 0.05?
d. Use the (full) model to determine compensation for a manager having 15 years with the company, a graduate degree, and a business-unit profit of $4,800(000) last year
