A local eatin 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 30 minutes. The owner has randomly selected 16 customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 30 minutes. The Pvalue for the test was found to be 0.029
State the correct conclusion.
A) The pvalue is large so we reject H0. We have sufficient evidence to say that mean delivery time exceeds 30 minutes.
B) The pvalue is small so we fail to reject H0. We do not have sufficient evidence to say that mean delivery time exceeds 30 minutes.
C) The pvalue is large so we fail to reject H0. We do not have sufficient evidence to say that mean delivery time exceeds 30 minutes.
D) The pvalue is small so we reject H0. We have sufficient evidence to say that mean delivery time exceeds 30 minutes.

a = 0.03
a = .05

a =
0.02
0.01
0.025
Then fail to reject the H0.
