A university wants to start placing coupons on admission tickets to basketball games in an effort to increase concession sales. They decide to test different versions of coupons. Over the course of the next basketball season, they will place a coupon for popcorn on the back of tickets at 10 games, a coupon for soda on the back of tickets at 10 games, and a coupon for hotdogs on the back of tickets at 10 games. They will record concession sales at each game and calculate an average of concession sales for each coupon type. They want to determine whether or not coupon type leads to significant differences in concession sales. They must use ANOVA to test this. O True O False
