Question

a local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. the owner of the store has determined the home delivery will be successful if the average time spent on deliveries does not exceed 27 minutes. The owner has randomly selected 25 customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 27 minutes. Suppose the p-value die the test was found to be .0268. State the correct conclusion. A). Alpha= .03, we fail to reject H0 B) Alpha= .05, we fail to reject H0 C) Alpha= .02, we reject H0 D) Alpha= .025, we fail to reject H0 a local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. the owner of the store has determined the home delivery will be successful if the average time spent on deliveries does not exceed 27 minutes.

Explanation / Answer

H0:u<=27mins, Ha:u>27mins

pvalue=0.0268

We reject H0 if pvalue<alpha

Hence a)Alpha=0.03->Hence as pvalue<0.03,we reject H0->Hence a)is false

b)Alpha=0.05->pvalue<0.05,we reject H0->Hence b) is false

c)Alpha=0.02->pvalue>0.02->We fail to reject H0->Hence c)false

d)Alpha=0.025->pvalue>0.025->We fail to reject H0->Hence d) is true
