QUESTION 34
1. One of the managers had by this time developed some interest in determining if there was a generalized equation that would possibly predict the “average purchase price” of a customer.  If the important factors could be isolated,  that might lead to a better defining of the “target market” of customers.  After much discussion,  the managers decided that they would like to determine if the purchase price by a customer might be related to their age (do younger women buy more make-up?), or the number of children they have (do women with fewer children buy more make-up), and the time of day that the customer is contacted (something that a sales program might emphasize) and finally whether the customer is employed or not (since once that fact is known, the marketing program might be redirected to a given market segment).
NOTE:  Only consider the independent variables mentioned,  that is,  age, number of children, time of day, and employment status.  Also,  be sure to only include statistically significant factors in the equation.  Be sure to make indicator variables when necessary.
Using stepwise regression to find the best equation possible (use F default values) ,  what is the best multivariate model for the problem.

a.
Purchase Price = 25.64 + .032 Age – .45 No. of Children – 1.63 Time of Day

b.
Purchase Price = 27.16 -.84 No. of Children – 1.95 Time of Day1

QUESTION 35
1.            Once you have used stepwise regression to find the best model,  you should do a regular regression with just the indicated variables in the model.  Do that now.
Based on the correct model, what percent of the variation in purchase price can be related to the significant factors identified?

a.
5.84%

b.
25.5%
