The probability that a randomly selected man from the certain age group runs slower than 5.66 mph is 0.2119. (You can check this, for practice, but it's true.) Calculate the probability the man runs between 5.66 and 8.65 mph, using this and your answer to the previous question. To help you accomplish this, consider the following three pictures of areas under the normal bell curve. This depicts the probability the man is slower than 8.65 mph. -3 -2 - 1 0 1 2 3 This depicts the probability the man is slower than 5.66 mph.
