Question 366804
the heights of female basketball players produce normal distribution, with a mean of 68 inches and standard deviation of 2 inches. what is the probability of randomly selected female player is more than 66.5 inches? 
if you could please let me know what Tales or keys are used no the calculator to arrive at the answer if at all possible. 
----------
z(66.5) = (66.5-68)/2 = -0.75
---
P(x > 66.5) = P(z > -0.75) = normalcdf(-0.75,100) = 0.7734
-----
Calculator talk.
To get P(z > -0.75)
2nd/DIST
#2 to get normalcdf(
Enter -0.75,100
--------------------------------------
That gives you the area under the normal curve
from 0.75 standard deviations to the left of 
the mean or zero to 100 standard deviations to
the right of the mean of zero.
--------------------------------------
ENTER
You should see the following on your screen: .773373
