Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 261 feet and a standard deviation of 42 feet. Let X be the distance in feet for a fly ball. a. What is the distribution of X? X ~ N(E,E) b. Find the probability that a randomly hit fly ball travels less than 280 feet. Round to 4 decimal places. l:] c. Find the 80th percentile for the distribution of distance of fly balls. Round to 2 decimal places. Hint
