The same data set from exercise 13.19 also has gender information for each engineer. The binary variable Male = 1 indicates the engineer is male and Male = 0 indicates the engineer is female. Run the regression with Salary as the response variable and Years, YearsSq, Male, and Years 3 Male as the explanatory variables. Report the p-values for the binary variable Male and the interaction term Years 3 Male. Are these two variables significant? Use α = .10.
