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 ~(_____,_____)
= X ~ N (250, 50)
a. If one fly ball is randomly
chosen from this distribution, what is the probability that this ball traveled
fewer than 220 feet?
Find the probability.
b. Find the 80th percentile of
the distribution of fly balls.
P(X <= x) = .80
X
