Edition 6ISBN: 130527010XUse the data in GPA1.RAW for this exercise.
(i) Add the variables mothcoll and fathcoll to the equation estimated in (7.6) and report the results in the usual form. What happens to the estimated effect of PC ownership? Is PC still statistically significant?
(ii) Test for joint significance of mothcoll and fathcoll in the equation from part (i) and be sure to report the p-value.
(iii) Add hsGPA2 to the model from part (i) and decide whether this generalization is needed.

Step 1 of 7
Consider the data GPA1.RAW to solve the subparts.
(i)
Then multiple linear regression model including all the four explanatory variables is given as:
Where, the intercept 
is the predicted value of 
when the entire
are equal to zero and
are the slope coefficient. To do the regression analysis adds the variables and the variables mothcoll and fathcoll in the regression equation 7.6 of the text book.
