Question

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 if the average time spent on the deliveries does not exceed 33 minutes. The owner has randomly selected 21 customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 33 minutes. Suppose the P-value for the test was found to be 0.0270. State the correct conclusion

Answer 1

The average time spent on the deliveries does not exceed 33 minutes.

i.e. it is greater than 33.

The null & alternative hypothesis:

Ho:- The average time spent on the deliveries does not exceed 33 minutes.

vs

Ha: The average time spent on the deliveries exceeds 33 minutes.

P-value = 0.0270

Level of significance = 0.05

Reject Ho if p-value < 0.05

Here p-value = 0.027 < 0.05

So we reject Ho.

we may conclde that the average time spent on the deliveries exceeds 33 minutes.

There is no possibility of starting to deliver pizzas.
