Product testers for a radio manufacturer routinely select a sample of units from the production line and test circuit integrity by subjecting each unit to extreme vibrations that are approximately triple the most violent shaking they are ever likely to encounter in the field. For the most recent five radios tested, the number of minutes until failure was found to be 15, 79, 68, 10, and 17 minutes. Using the 0.05 level of significance, apply the Kolmogorov-Smirnov test for normality in examining whether the pop ulation of failure times might be normally distributed.
