In its continuing study of the 3- For- All subscription solicitation process, a marketing department team wants to test the effects of two types of structured sales presentations ( personal formal and personal informal) and the number of hours spent on telemarketing on the number of new subscriptions. The staff has recorded these data for the past 24 weeks in AMS13.

Analyze these data and develop a multiple regression model to predict the number of new subscriptions for a week, based on the number of hours spent on ­telemarketing and the sales presentation type. Write a report, giving detailed findings concerning the regression model used.
