A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time spent on a delivery does not exceed 27 minutes. The owner has randomly selected 25 customers and delivered pizzas to their homes in order to test whether the mean delivery time actually exceeds 27 minutes. Suppose the p-value for the test was found to be .0268. State the correct conclusion

a. at =.03, we fail to reject H0
b. at =.05, we fail to reject H0
c. at = .02 we reject H0
d. at =.025 we fail to reject H0

Solution

P-Value: Two Tailed ( double the one tail ) - Ha = 0.0268
Hence Value of P0.02 < 0.0268,Here we Reject Ho
