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. Click here to view page 2 of the standard normal distribution table. Of the 400 cars, approximately cars will be traveling slower than 62 mph. (Round to the nearest whole number as needed.)
