Provide an appropriate response.Assume that adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler test). Find the probability that a randomly selected adult has an IQ between 90 and 120 (somewhere in the range of normal to bright normal). Make sure to first define variable X before calculating the probability (4pts) Define X= Prob=
