Useful Life The lifetime of a certain type of battery is normally distributed with a mean of 400 hours and a standard deviation of 24 hours. You purchased one of the batteries, and its useful life was 340 hours. How far, in standard deviations, did the useful life of your battery fall short of the expected life? Use a symbolic integration utility to approximate the percent of all other batteries of this type with useful lives that exceed that of your battery.
