2) (3 points) Fifty-five customers of a large-chain grocery store are asked to fill out an in-store survey. One of the questions on the survey asks about the use of coupons (yes or no), while another question asks how much money the customer spent on groceries during that specific trip. A store management hypothesizes that people that use coupons actually spend more money, on average. HO Ha Test Statistics

1. Data from customer reward cards at a major grocery store chain show that of all customers who purchase Coke in their weekly grocery shopping, 90% will purchase it again the next week while 10% will purchase Pepsi instead. Of all customers who purchase Pepsi one week, 80% will purchase it again the next week and 20% will purchase Coke. Assuming that the probability that any given customer purchases Coke (or Pepsi) in any week depends only on their purchase...
