A new battery supposedly with a charge of 1.60 volts actually has a voltage with a uniform distribution between 1.45 and 1.65 volts. (a) What is the cumulative distribution function of the voltage? (b) If a box contains 35 batteries, what is the expectation and variance of the number of batteries in the box with a voltage less than 1.60 volts?
