Eagle Outfitters is a chain of stores specializing in outdoor apparel and camping gear. They are considering a promotion that involves mailing discount coupons to all their credit card customers. This promotion will be considered a success if more than 10% of those receiving the coupons use them. Before going national with the promotion, coupons were sent to a sample of 100 credit card customers. Develop hypotheses that can be used to test whether the population proportion of those who will use the coupons is sufficient to go national. Use =.05 to conduct your hypothesis test. Should Eagle go national with the promotion?
