8. Last year, the mean running time for a certain type of flashlight battery was 8 hours. This year, the manufacturer has introduced a change in the production method which he hopes will increase the mean running time. A random sample of 36 of the new light bulbs was obtained and the mean running time was found to be 8.3 hours with s=1 hours. Do the data provide sufficient evidence to conclude that the mean running time, u, of the...
