200 randomly selected Americans are asked if they smoke cigarettes. Then the results of this procedure can be treated as a binomial distribution. 

Suppose that the speed at which cars go on the freeway is normally distributed with mean 66 mph and standard deviation 8 miles per hour. Let X be the speed for a randomly selected car.  Round z-scores to 2 decimal places. Round all answers to 4 decimal places. a. If one car is randomly chosen, find the probability that it is traveling more than 62 mph. [a] b. If one of the cars is randomly chosen, find the probability that it is traveling between 65 and 68 mph. [b] c. 77% of all cars travel at least how fast on the freeway? [c]

If Z is a random variable from a standard normal distribution and if P(Z > c) = 0.34, then P(Z < -c) = 0.34
