Answer:
Step-by-step explanation:
Assuming that:
the promotion will be considered to be a success if more than 10% use the coupons received.
and coupons are sent to 100 credit card customers.
Then, the null hypothesis and alternative hypothesis is:
sample size n = 100
Using the eagle file data;
the no of people in the sample who use the coupon = 13
then,
Test statistics can be computed as:
At ∝ = 0.05
Since, P-value is greater than ∝, then we fail to reject .
Therefore, Eagle should not go with the promotion; a larger sample should be taken.
