classify the conclusion of the significance test as a type i error, a type ii error, or no error. in the past, the mean lifetime for a certain type of flashlight battery has been 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 non-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.
