question 5

5) In the past, the mean running time for a certain type of flashlight battery 5) has been 9.0 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=9.0 hours H : H>9.0 hours where u is the mean running time of the new batteries Suppose that the results of the sampling lead to rejection of the null hypothesis. Classify that conclusion as a Type I error, a Type II error, or a correct decision, if in fact the mean running time has not increased. A) Correct decision B) Type II error C) Type I error
