Magazine Sales Narrative
A publisher is studying the effectiveness of advertising to sell a woman's magazine. She wishes to investigate the relationship between the number of magazines sold (10,000s), the "reach" (proportion of the population who see at least one advertisement for the magazine), and the average income of the target market ($1000s). The publisher suspects people at certain income levels might be more susceptible to this advertising campaign than others. Preliminary studies show there is no evidence of a quadratic relationship between sales and either of the other two variables. Use the output below to answer the questions.
The regression equation is
Sales = 3.1 + 10341 Reach + 0.871 Income + 3.256 Reach*Income S = 8.43 R-sq = 82.4%
Analysis of Variance
-Refer to Magazine Sales Narrative. Write the model used for the regression.
