Question

At a University of Colorado woman's home basketball game, a random sample of 25 con- cession purchases showed a mean of $7.12 with a standard deviation of $2.14. For the next week's home game, the admission ticket had a discount coupon for popcorn printed on the back. A random sample of 25 purchases from that week showed a mean of $8.29 with a standard deviation of $3.02. Was there an increase in the average concession stand purchases with the coupon? Assume unequal variances and use α = .05.
