Your company has developed a probability of purchase model based upon the number of promotions to which a customer has been exposed. The dependent variable is the probability that a customer will make a purchase within the following week (0-1). The independent variable is the number of promotions to which the customer has been exposed over the past month.. The model appears as follows: Probability of Purchase = .2 + .075 (# of promotions exposed in past month) Interpret the associated 95% confidence interval if it is .4 - .6. Interpret the associated 95% prediction interval if it is: .35 - .65.
