Chapter 4, Problem 4.1.2(choose chapter or problem)
A new battery supposedly with a charge of 1.5 volts actually has a voltage with a uniform distribution between 1.43 and 1.60 volts. (a) What is the expectation of the voltage? (b) What is the standard deviation of the voltage? (c) What is the cumulative distribution function of the voltage? (d) What is the probability that a battery has a voltage less than 1.48 volts?(e) If a box contains 50 batteries, what are the expectation and variance of the number of batteries in the box with a voltage less than 1.5 volts?
