Question 1179314: Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 259 feet and a standard deviation of 40 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 216 feet?
P(fewer than 216 feet) =
b) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled more than 234 feet?
P(more than 234 feet) =
I need the steps please. Thank you.

You can put this solution on YOUR website! Use VARS2normalcdf(0,216,259,40) ENTER for 0.1412. You put in the left interval, the right interval, the mean the sd, and hit ENTER. 14.12%
for 234
do normalcdf(234,1000,249,40). Nothing magic about 1000.Anything more than 6 sd s will be sufficient.
value is 0.7340 or 73.40%.
