Question

Kelsey surveyed the 17 shoppers who spent the most at her boutique last month.

Is this a random sample of the shoppers at the boutique?


PLLLLLLLSSS! I NEED THIS ASAP!

Answer 1

Answer: No

Reason: The sample is biased toward the people who spent the most money. It leaves out people who didn't spend as much money, so the sample is not representative. A better survey method would be to randomly select names out of a hat.
