Eagle Outfitters is a chain of stores specializing in outdoor apparel and camping gear. It is considering a promotion that involves mailing discount coupons to all its 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.a. Develop hypotheses that can be used to test whether the population proportion of those 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 $\alpha=.05$ to conduct your hypothesis test. Should Eagle go national with the promotion?

a. $H_{0} : p \leq 10 \%=0.10, H_{a} : p>0.10$b. 0.13c. There is sufficient evidence to support the claim that Eagle should gonational with the promotion.

a store wants to try using a coupon strategy if they consider their coupons successful, with more than 10% of the customers who received coupons actually use them. So to test the strategy than Male 100 coupons out to 100 of the customers to see if more than 10% would use them. So we're supposed to use this 100 customer test to see if the strategy would be successful. Part A is to develop a hypothesis to test whether the coupon strategy is successful so it would be successful. So this is that alternative hypothesis. If more than 10% he was the coupons and unsuccessful, That's the no hypothesis, 10% or less use the coupons. Now in Part B, there is a file that accompanies the textbook, which has the data for this. For this 100 coupon test from the file were supposed to develop a point estimate. So the best point estimate is the number of people in the file who actually use the coupon divided by the total number. So there were are 100 people that this was tried with, and the number that said yes is 13 so from this, our sample proportion is 0.13 and that is the best point estimate of the proportion of people who receive coupons who use them. And then for part C, it says, using an Alfa of 0.5 Where to conduct our hypothesis test. So this is an upper tail tests that we're trying to see if the alternative hypothesis is greater than 10%. So our Zed's car is getting by this and test statistic comes out to one so we could go to the table, and from that table we can look up. The area that is to the left of authentic was one, and that is 0.8413 But because we're conducting an upper tail test, we want the area to the right of the test statistic. So RPI value is one minus 0.8413 comes out 200.1587 and now to conduct the test, we can say that P value is bigger than Alfa, and therefore we fail to reject that. No hypothesis, and you can summarize by saying we do not have sufficient evidence to suggest the coupon strategy works
