Background: IQ test scores based on the Wechsler Adult Intelligence Scale (WAIC) are approximately Normally distributed with a mean of 100 and a standard deviation of 15.
Question: An adult whose IQ score is within the central 50% of all adult IQ scores is said to have "normal" or "average" intelligence. Therefore, an adult of normal intelligence would have an IQ score between what two values?

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) is a common “IQ test” for adults. The distribution of WAIS scores for persons over 16 years of age is approximately normal with mean 100 and standard deviation 15. You wish to determine the probability that a randomly chosen individual has a WAIS score of 105 or higher. To do this, you first need to standardise to a Z-score. You now sample 60 people at random. State whether the following is true or false:...

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 Weschler Intelligence Scale (IQ) for Children is approximately normally distributed with a mean of 100 and a standard deviation of 15. c) What IQ score would place a child in the top 3% of all IQ scores? d) What would be the range of scores that represent the middle 90% of all children's IQ score? I need to know how to calculate them with TI-84 calculator. Thank you!!
