8) Some boxes of a certain brand of popcorn include a coupon for a free movie theater ticket inside the box. The company that makes the popcorn claims that a coupon can be found in 30 percent of the boxes. However, based on their experiences eating this cereal at home, a group of students believes that the proportion of boxes with coupons is less than 0.3. This group of students purchased 80 boxes of the popcorn to investigate the company's claim. The students found a total of 19 coupons for free movie theater ticket in the 80 boxes. Suppose it is reasonable to assume that the 80 boxes purchased by the students are a random sample of all boxes of this popcorn. Based on this sample, is there support for the students' belief that the proportion of boxes with coupons is less than 0.3 ? Provide statistical evidence to support your answer.
