Question

Question 11 In the past, the mean running time for a certain type of flashlight battery has been 8.0hours 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: H0 u 8.0 hours vs. Ha > 0 hours where is the mean running time of the new batteries. Explain the meaning of a Type I error A Type I error would occur if, in fact, > 8.0 hours, but the results of the sampling fail to lead to that conclusion. O A Type I error would occur if, in fact, -8.0 hours, but the results of the sampling do not lead to rejection of that fact. O A Type 1 error would occur if, in fact, -8.0 hours, but the results of the sampling lead to the conclusion that > 80 hours. O A Type 1 error would occur if, in fact, > 8.0 hours, but the results of the sampling lead to the conclusion that

Explanation / Answer
