A police radar gun is used to measure the speeds on a highway. The speeds are normally distributed with a mean of 62 mi/hr and a standard deviation of 12 mi/hr. (a) Draw the appropriate shaded region of the normal distribution. Find the probability that a randomly selected car is driving at a speed between 60 mi/hr and 70 mi/hr?  b) Find the speed at the 95th percentile.
