Assume that adults have IQ scores that are normally distributed with a mean of μ=100 and a standard deviation σ=20.

Question

Find the probability that a randomly selected adult has an IQ less than 132.

The probability that a randomly selected adult has an IQ less than

132 is ...

​(Type an integer or decimal rounded to four decimal places as​ needed.)

Answer 1

Prob( X < 132) = Prob ( z < (132-100)/20) = Prob ( z < 32/20) =Prob( z ,< 8/5) = 0.945201 = 94.5201%
