In the past, the mean running time for a certain type of flashlight battery has been8.9 hours The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean running time has increased as a result. The hypotheses are:

H₀: = 8.9 hours

H_a: > 8.9 hours

Identify the Type I error

A)Reject the claim that the mean running time is 8.9 hours when actually the mean running time is 8.9 hours.

B)Fail to reject the claim that the mean running time is 8.9 hours when actually the mean running time is 8.9 hours.

C)Fail to reject the claim that the mean running time is 8.9 hours when actually the mean running time is greater than8.9 hours.

D)Reject the claim that the mean running time is 8.9 hours when actually the mean running time is 8.9 hours
