Suppose that the speed at which cars go on the freeway is normally distributed with mean 69 mph and standard deviation 8 miles per hour. Let X be the speed for a randomly selected car.a. What is the distribution of X? X ~ N(,)b. If one car is randomly chosen, find the probability that it is traveling more than 71 mph. Round to 4 decumal places. c. If one of the cars is randomly chosen, find the probability that it is traveling between 72 and 75 mph. Round to 4 decimal places.
