a. Determine the estimated linear regression equation relating the dependent and independent variables.
b. Is the regression equation you found significant? Test at the a = 0.05 level.
c. Determine both the residuals and standardized residuals. Is there anything about the residuals that would lead you to question whether the assumptions necessary to use regression analysis are satisfied?
