Question 437222: An IQ test is approximately normally distributed witha mean of 100 and standard deviation of 15.
What is the probability that a randomly chosen individual has an IQ score of 110 or higher? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! An IQ test is approximately normally distributed witha mean of 100 and standard deviation of 15.
What is the probability that a randomly chosen individual has an IQ score of 110 or higher?
--------------
z(110) = (110-100)/15 = 2/3
----
P(x>= 110) = P(z >= (2/3)) = normalcdf(2/3,100) = 0.2525
