Pelican Stores, a division of National Clothing, is a chain of women's apparel stores operating throughout the country. The chain recently ran a promotion in which discount coupons were sent to customers of other National Clothing stores. Data collected for a sample of 100 in-store credit card transactions at Pelican Stores during one day while the promotion was running are contained in the case study data file.

Problem

Pelican's management would like to use this sample data to learn about its customer base and to evaluate the promotion involving discount coupons.
