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

The following table contains companies stratified by industry type into rows and grouped vertically by Stock Price at close on 20 September 2023 (clusters)

Companies Used in Sample
Stock Price	Under $50	$50 to under $100	$100 to under $200	Over $200
apparel, fitness, footwear, retail	american eagle outfitters footlocker nordstrom	puma nike adidas crocs	target	the home depot costco
