Managing Ashland MultiComm Services 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 telemarket- ing on the number of new subscriptions. The staff has recorded these data for the past 24 weeks in AMS14 .

Write a report, giving detailed findings concerning the regression model used. n
