Stanford–Binet IQ Test scores are normally distributed with a mean score of 100 and a standard deviation of 15. (10 points) Sketch the distribution of Stanford–Binet IQ test scores. Write the equation that gives the z score corresponding to a Stanford–Binet IQ test score. Sketch the distribution of such z scores. Find the probability that a randomly selected person has an IQ test score Over 145. Under 91.

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,...
