Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 244 feet and a standard deviation of 48 feet. We randomly sample 49 fly balls. Part (a) If X = average distance in feet for 49 fly balls, then give the distribution of X. Round your standard deviation to two decimal places. X-N Part (b) What is the probability that the 49 balls traveled an average of less than 234 feet? (Round your answer to four decimal places.) Sketch the graph. Scale the horizontal axis for X. Shade the region corresponding to the probability. O O Part (c) 230 230 240 240 250 250 260 260 ^ 240 230 230 240 250 250 Find the 70th percentile of the distribution of the average of 49 fly balls. (Round your answer to two decimal places.) ft 260 260
