In the past, the mean lifetime for a certain type of flashlight battery has been lower than desired. The manufacturer has introduced a change in the production method and wants to perform a significance test to determine whether the mean lifetime has increased as a result. The hypotheses are: H0: μ = 9.6 hours Ha: μ > 9.6 hours Suppose that the results of the sample lead to nonrejection of the null hypothesis.
a) Classify that conclusion as a Type I error, a Type II error, or a correct decision, if in fact the mean running time has increased.
