In the past, the mean running time for a certain type of flashlight battery has beenThe 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: = 9.8 hours

H₁: > 9.8 hours

where is the mean running time of the new batteries

Suppose that the results of the sampling fail to 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 increased.

1. Type I
2. Correct decision
3. Type II
