1) The estimated regression equation was
Gross revenue=79.7364+1.9434 TV Advertising+2.2029 News Advertising
R square value=95.10%,
2) When television advertising was the only independent variable, the regression equation becomes
Gross revenue=89.4686+1.2541 TV Advertising
R square value=41.95%% . Since the R square value is almost half the earlier, our conclusion is
Yes, because greater variability is explained when both independent variables are used
