Suppose IQ scores are approximately normally distributed with a mean  of 100 and a standard deviation  of 15. Answer the following questions   If an individual is randomly selected from the population, then what is the probability that his/her IQ is between 110 and 130?  (Your answer should be left as a decimal expressed to four decimal places.
