In the past, the mean running time for a certain type of flashlight battery has been 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: μ = 8.9 hours
H_a: μ > 8.9 hours
Identify the Type I error.

▸ Fail to reject the claim that the mean running time is 8.9 hours when actually the mean running time is  greater than s.

▸ Reject the claim that the mean running time is 8.9 hours when actually the mean running time is
s.

▸ Fail to reject the claim that the mean running time is 8.9 hours when actually the mean running time is  s.

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