Solve the problem. Round three decimal places as needed. Intelligence Quotient (IQ) scores are normally distributed with a mean of 100 and a standard deviation of 15. If 9 people are randcomly selected, what is the probability they will have a mean IQ score between 105 and 110?(round three decimal places)
