a. Is there a significant linear relationship between sales and advertising? If so, is it fair to conclude that advertising causes sales to increase?
b. If a regression model were developed using sales as the dependent variable and advertising as the independent variable, determine the proportion of the variation in sales that would be explained by its relationship to advertising. Discuss what this says about the usefulness of using advertising to predict sales.
