A standard IQ test, the Stanford-Binet, states that the average IQ score for adults is 100 with a standard deviation of 15. For a randomly chosen adult, u= O= 13. What is the probability that her score will be 132? Use z = - XM Z = - X = Z = p = CAP 0.00 0.01 0.02 0.03 2.1 0.9821 0.9826 0.9830 0.9834 2.2 0.9861 0.9864 0.9868 0.9871 14. What proportion of adults have a higher IQ? 15. Would you expect an adult with an IQ of 105 to have a positive z-score or a negative z-score? WHY
