1. The Hyatt Gold Passport is a card designed to allow frequent guests at Hyatt hotels to enjoy privileges similar to the ones enjoyed by frequent air travelers. When the program was initiated, a random sample of 15 Hyatt Gold Passport members were asked to rate the program on a scale of 0 to 100 and also to rate (on the same scale) an airline frequent-?ier card that all of them had. The results are as follows.

Hyatt card: 98, 99, 87, 56, 79, 89, 86, 90, 95, 99, 76, 88, 90, 95
Airline card: 84, 62, 90, 77, 80, 98, 65, 97, 58, 74, 80, 90, 85, 70

Is the Hyatt Gold Passport better liked than the airline frequent-?ier card by holders of both cards? Explain.

2. Two telecommunication systems are to be compared. A random sample of 14 users of one system independently rate the system on a scale of 0 to 100. An inde- pendent random sample of 12 users of the other system rate their system on the same scale. The data are as follows.

System A: 65, 67, 83, 39, 45, 20, 95, 64, 99, 98, 76, 78, 82, 90

System B: 45, 57, 76, 54, 60, 72, 34, 50, 63, 39, 44, 70
