Suppose you want to predict sneaker sales on the basis of advertising expenditures and sneaker color, red or blue. You create one dummy variable for the sneaker color (Red = 1 for red sneakers and Red = 0 for blue sneakers) and run the regression on data collected over ten years using the dummy variable and advertising expenditures as your independent variables. The equation you obtain is:
Sales = 631,085 + 533,024(Red) + 50.5(Advertising)
a. How would you interpret the regression model?
b. How would you interpret the coefficient for red sneakers?
