A new battery supposedly with a charge of 1.5 volts actually has a voltage with a uniform distribution between 1.42 and 1.58 volts. (Round your answers to 3 decimal places, if needed.) (a) What are the expected value and standard deviation of voltage? Expected value = I: Standard deviation = I: (b) What is the probability that a battery has a voltage less than 1.45 volts? :1 (c) If a box contains 40 independent batteries, what are the expected value and variance of the number of batteries in the box with a voltage less than 1.55 volts? Expected value = I: Variance =
