Question

In order to determine the most popular ride at Cedar Point, a researcher interviewed people in the parking lot as they were leaving Cedar point. Assuming that everyone went on the rides that they like, is this a random sample? If not, why is it not?
a. no, because it does not include other parks
b. no, because some of the lines may have been long
c. no, because some of the rides may be new
d. yes

ANSWER: D

Answer 1

yes it is a random sample because it is unlikely that everybody leaving the park went on every single ride. Since they didn't go on every ride, they can only choose their favorite from the rides they did go on.
