Question 224243: a set of data is normally distributed with a mean of 50 points and a standard deviation of 10 points. what percent of the data is greater then 60. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! a set of data is normally distributed with a mean of 50 points and a standard deviation of 10 points. what percent of the data is greater then 60.
------------
Find the z-value of 60
z(60) = (60-50)/10 = 10/10 = 1
-------------------------
P(x>60) = P(z>1) = normalcdf(1,100) = 0.1587
-------------
0.1587 is gotten using a TI calculator.
Another way to get that result would be
to us a z-chart.
Hope this helps.
