The Wechsler Adult Intelligence Scale (WAIS) intelligence quotient (IQ) tests are the primary clinical instruments used to measure adult and adolescent intelligence (16-89 years old). The distribution of IQ supposedly follows a normal distribution curve with mean 100 and standard deviation 15. IQ scores between 70 and 130 run the gamut from "borderline" intelligence to very superior intelligence. Using the empirical rule, what is the probability a randomly chosen adult has an IQ score between 70 and 130? 0.95 0.68...
