Question 1077551: 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 36 minutes. The owner has randomly selected 20
customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 36 minutes. Suppose the P-value for the test was found to be
0.0275. State the correct conclusion.

A.
At α=0.05, we fail to reject H0.

B.
At α=0.02, we reject H0.

C.
At α=0.03, we fail to reject H0.

D.
At α=0.025, we fail to reject H0.

I think it is A but I'm not for sure.

you would reject the null hypothesis if the p-value of the test is less than the critical p-value.

alpha is the critical p-value in this test.

the p-value of the test is .0275

.0275 is less than .05 so you would reject the null hypothesis.

.0275 is greater than .02 so you would fail to reject the null hypothesis.

.0275 is less than .03 so you would reject the null hypothesis.

.0275 is greater than .025 so you would fail to reject the null hypothesis.

compare what you find with what is stated.



              stated              find              statements match

A             fail                reject                no
B             reject              fail                  no
C             fail                reject                no
D             fail                fail                  yes *****

selection D appears to be the correct statement since what you found and what was stated agree while what you found and what was stated don't agree in any of the other selections.
