In the past, the mean running time for a certain type of flashlight battery has been 9.9 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: Ho: H = 9.9 hours Ha u> 9.9 hours where u is the mean running time of the new batteries. Suppose that the results of the sampling lead to nonrejection of the null hypothesis. Classify that conclusion as a Type I error, a Type Il error, or a correct decision, if in fact the mean running time has increased.
