In 2000, the average duration of long-distance telephone calls originating in one town was 9.4 minutes. Five years later, in 2005, a long-distance telephone company performs a hypothesis test to determine whether the average duration of long dash distance phone calls has changed from the 2000 mean of 9.4 minutes. The hypotheses are: Upper H 0 : mu equals 9.4 minutes Upper H Subscript a Baseline : mu not equals 9.4 minutes where mu is the mean duration, in 2005, of long-distance telephone calls originating in the town. 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 duration of long-distance phone calls has changed from the 2000 mean of 9.4 minutes.
