Card 13 / 25:
Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet.
If X = distance in feet for a fly ball, then X ~ _____(_____,_____)If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 220 feet? Sketch the graph. Scale the horizontal axis X . Shade the region corresponding to the probability. Find the probability.Find the 80 th percentile of the distribution of fly balls. Sketch the graph, and write the probability statement.
