Ninth,consider the relationshipbetween the alternative distribution t(5) and the simulated power. Figure 9 summarizes the power analysis for the t(5) alternative distribution. This is the only one symmetric distribution used in the
power analyses. All five exponentiality tests quickly detected non-exponentiality. For sample sizes at least 15, the powers for all five tests were almost identical which were close to 1. The range of the powers was found to be very narrow across all sample sizes for a fixed significance level
