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 38 minutes. The owner has randomly selected 24 customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 38 minutes. Suppose the​ P-value for the test was found to be 0.0265. State the correct conclusion. A. At alphaequals​0.03, we fail to reject Upper H 0. B. At alphaequals​0.025, we fail to reject Upper H 0. C. At alphaequals​0.05, we fail to reject Upper H 0. D. At alphaequals​0.02, we reject Upper H 0.

Answer 1

Given dat

n = 24

p value = 0.0265

A. At alpha equals​0.03, we fail to reject Upper H 0.

B. At alpha equals​0.025, we fail to reject Upper H 0.

C. At alpha equals​0.05, we fail to reject Upper H 0.

D. At alpha equals​0.02, we reject Upper H 0.

p value = 0.0265 > alpha = 0.025  , we fail to reject Upper H 0.

p value = 0.0265 < alpha = 0.03 Reject Ho

p value = 0.0265 < alpha = 0.05 Reject Ho

p value = 0.0265 > alpha = 0.02 fail to reject Ho

Hence Option B is correct

p value = 0.0265 > alpha = 0.025  , we fail to reject Upper H 0.
