Work in groups on these problems. You should try to answer the questions without referring to your textbook. If you get stuck, try asking another group for help.

Student Learning Outcomes

The student will demonstrate the simple random, systematic, stratified, and cluster sampling techniques.
The student will explain the details of each procedure used.

In this lab, you will be asked to pick several random samples of restaurants. In each case, describe your procedure briefly, including how you might have used the random number generator, and then list the restaurants in the sample you obtained.

Note 1.7.1

The following section contains restaurants stratified by city into columns and grouped horizontally by entree cost (clusters).
