3. (3) Suppose we randomly select a driver from the pool of all American drivers. Draw a reasonable probability distribution for the number of miles that person drove during the past twelve months. Note: According to data from the U.S. Department of Transportation, the average American driver puts in 13,474 miles behind the wheel each year. While the Department of Transportation does not report any information on the variation in the number of miles driven, one source estimates the standard deviation to be 9,944 miles. a. Does this case involve a discrete or a continuous random variable? b. Draw a graph of the distribution. Be sure that you label the axes of your graph and show reasonable numbers on the axbs. This distribution involves a. .. El discrete random variable CI continuous random variable
