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.

who will use the coupons is sufficient to go national.
b. The file Eagle contains the sample data. Develop a point estimate of the population
proportion.
c. Use a  .05 to conduct your hypothesis test. Should Eagle go national with the
promotion?
