A survey asked 2000 people whether or not they frequently exceed the speed limit. The collected data is summarized in the following contingency table. The goal is to determine if there is a difference in the population proportion that say “yes” when comparing those who are under 40 years in age to those who are at least 40 years in age.

Age 40 and above 450 (45%) 550 1000
Total 1050 950 2000
a. What is the response variable in this problem?
