A study of the amount of time it takes a hiker to hike to the bottom of the Grand Canyon and back to the top shows that the mean is 10 hours and the standard deviation is 2 hours. If 9 hikers are randomly selected, find the probability that their mean hiking time is less than 9 hours. P(x < 9 hours) = .
