What is the age distribution of promotion-sensitive shoppers? A supermarket super shopper is defined as a shopper for whom at least 70% of the items purchased were on sale or purchased with a coupon. Age range, years Midpoint x Percent of super shoppers LAUSE SALT 18-28 23 10% 29-39 40-50 34 41% 45 51-61 56 23% 13% 62 and over 67 13% For the 62-and-over group, use the midpoint 67 years. (a) Using the age midpoints x and the percentage of super shoppers, do we have a valid probability distribution? Explain. O No. The events are distinct and the probabilities sum to 1. O Yes. The events are distinct and the probabilities sum to 1. O No. The events are indistinct and the probabilities to more than 1. O Yes. The events are distinct and the probabilities do not sum to 1. O Yes. The events are indistinct and the probabilities sum to less than 1. (b) Use a histogram to graph the probability distribution of part (a). (Because the data table has summarized the data into categories, use SALT to create a bar chart.)
