Clаssify the cоnclusiоn оf the hypothesis test аs а Type I error, a Type II error, or a correct decision.In the past, the mean running time for a certain type of flashlight battery has been 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: μ = 9.2 hours Ha: μ > 9.2 hourswhere μ 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 II error, or a correct decision, if in fact the mean running time has increased.
Clаssify the cоnclusiоn оf the hypothesis test аs а Type I error, a Type II error, or a correct decision.A manufacturer claims that the mean amount of juice in its bottles is A consumer advocacy group wants to perform a hypothesis test to determine whether the mean amount is actually less than this. The hypotheses are: H0: μ = 16.1 ounces Ha: μ < 16.1 ounceswhere μ is the mean amount of juice in the manufacturer's bottles.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 amount of juice, μ, is less than
