Question 1170956: Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 243 feet and a standard deviation of 42 feet.
Use your graphing calculator to answer the following questions. Write your answers in percent form. Round your answers to the nearest tenth of a percent.
a) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 228 feet?
P (fewer than 228 feet) = %
b) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled more than 246 feet?
P(more than 246 feet) = %

You can put this solution on YOUR website!
the first is z < (228-243)/42 or -15/42 . that probability is 0.3605
for the other, z > 2ndVARS(246,500,243,42)ENTER for 0.4715 probability.
