Answer #1

1. The linear regression model is = 80.43+11.94*Industry-4.82*Private-2.62*Quality-4.07*Completed

The coefficient of Industry, Quality and Completed are significant at 5 percent level as the P-value is less than 0.05

The R-square is 0.3826 means the model is able to capture 38.26 percent of variation
