Question

The Publishers Information Bureau in New York City released magazine advertising expenditure data compiled by leading national advertisers. The data were organized by product type over several years. Shown here are data on total magazine advertising expenditures and household equipment and supplies advertising expenditures.
Using these data, develop a regression model to predict total magazine advertising expenditures by household equipment and supplies advertising expenditures and by (household equipment and supplies advertising expenditures). Compare this model to a regression model to predict total magazine advertising expenditures by only household equipment and supplies advertising expenditures. Construct a scatter plot of the data. Does the shape of the plot suggest some alternative models in light of Tukey’s four-quadrant approach? If so, develop at least one other model and compare the model to the other two previously developed.

Advertising Expenditures and Supplies Expenditures
