13.
An automobile manufacturer has 20 franchised dealers in a large metropolitan area. To study factors influencing the amount of customer traffic, data were collected on customer traffic per week, the amount of newspaper and TV advertising by each dealer (shown in $100s), the size of their physical facilities (in acres), and the location of the dealership (Urban, Suburban or Rural). .
Assume that the regression analysis resulted in the following results. (Note that a different data set was used to find these results than for earlier problems where the data were given.)
