The Wechsler Adult Intelligence Scale (WAIS) is the most common "IQ test." The scale of scores is set separately for each age group and is approximately normal, with mean 100 and standard deviation 15. People with WAIS scores below 70 are generally considered eligible to apply for Social Security disability benefits. By this criterion, what percent of adults are in this IQ category?

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...

The Stanford-Binet Intelligence Scale is an intelligence test, which, like many other IQ tests, is standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points. As an early intervention effort, a school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder. Determine the margin of error,...
