A company is considering two different TV ads for promotion of a new product. Two test markets with identical consumer characteristics are chosen and ad A is used in one and B in the other. In a random sample of 60 customers who saw ad A, 18 tried the product. In a random sample of 100 customers who saw ad B, 22 tried the product. At the 0.05 significance level, does this indicate that there is a difference in the effectiveness of ad A and B?
