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 ~ Part (b) What is the probability that the 49 balls traveled an average of less than 228 feet? (Round your answer to four decimal places.) Sketch the graph. Scale the horizontal axis for X. Shade the region corresponding to the probability. 220 230 240 250 260 220 230 240 250 260 220 230 240 250 260 220 230 240 250 260 Part (c) Find the 80th percentile of the distribution of the average of 49 fly balls. (Round your answer to two decimal places.) ft
