Question

Question 19 1 pts 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 At a -0.025, we fail to reject HO At a = 0.05, we fail to reject HO At -0.03, we fail to reject HO At a -0.02, we reject HO

Answer 1

Given that,

n=21

D.f=n-1

=21-1

D.f=20

P value =0.0270

P value is greater than $\alpha$ .

$\alpha$=0.025

Hence we fail to reject null hypothesis.
