Question

A restaurant chain's owners are trying to decide if they want to open up a franchise in your town. To help them decide, they want to find out how often people in your town go out to eat. A researcher interviews people leaving a local restaurant. Is there a bias in this sampling method? Explain.

Answer 1

This one is definitely biased. You are selecting from among people who DO go to restaurants at least occasionally. Some people just don't go to restaurants. And the more I think about the other question, that one is biased too because of the telephone.

Answer 2

ok thank you so much

Answer 3

uw!
