You can put this solution on YOUR website! Adult IQ scores are normally distributed with mean 100 and standard deviation 15. Randomly choose 1 adult. What is the probability the adult has IQ less than 112? Round your answer to 3 decimal places.
-------
z(112) = (112-100)/15 = 12/15 = 0.8
-------
P(x < 112) = P(z < 0.8) = 0.7881
