In a study of exercise, a large group of male runners walk on a treadmill for six minutes. Their heart rates in beats per minute at the end vary from runner to runner according to the ?(104,12.5) distribution. The heart rates for male nonrunners after the same exercise have the ?(130,17) distribution. (a) What percent of the runners have heart rates above 140? Give your answer to two decimal places. (b) What percent of the nonrunners have heart rates above 140? Give your answer to two decimal places.
