Assume that the speed of automobiles on an expressway during rush hour is normally distributed with a mean of 63 mph and a standard deviation of 10 mph. If 400 cars are selected at random, how many will be traveling slower than 52 mph? Click here to view page 1 of the standard normal distribution table.
