Identify the Type I error or Type II error as indicated.
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:
H
0: μ = 8.3 hours
H
a: μ > 8.3 hours
Identify the Type II error.
◦ Reject the claim that the mean running time is 8.3 hours when actually the mean running time is
s.
◦ Fail to reject the claim that the mean running time is 8.3 hours when actually the mean running time is
