Multiple Linear Regression
20. The Excel file Concert Sales provides data on sales dollars and
the number of radio, TV, and newspa-per ads promoting the concerts
for a group of cities. Develop simple linear regression models for
predict-ing sales as a function of the number of each type of ad.
Compare these results to a multiple linear regres-sion model using
both independent variables. State each model and explain R-Square,

(4 points) The marketing manager at Super Foods wants to develop a regression model to predict monthly sales per store of a power bar (in the number of power bars sold in a month) and to determine what variables influence the sales. Two variables are considered here: the price of the power bar, (in cents) and the monthly budget for the in-store promotional expenditures (in dollars). Data are collected from a sample of 20 stores in a supermarket chain and...
