CASE PROBLEM
Pelican Stores is a chain of woman’s apparel stores operating throughout the country. The chain
recently ran a promotion in which discount coupons were sent to customers of related stores. Data
collected for a sample of 100 in-store credit card transactions during one day in November 2002 are
given below. A nonzero amount for the discount variable indicates that the customer bought in the
promotional coupons and used them. For a very few customers, the discount amount is actually
greater than the sales amount (eg. Customer 4). Pelican’s management would like to use this sample
data to learn about its customer base and to evaluate the promotion involving discount coupons.
