Question: Assume IQ scores are normally distributed with a population mean of 100 and a population standard deviation of 15. A random sample of 64 individuals are randomly selected from the population.

A. Carefully graph and label the x-bar axis and the z-bar axis of the sampling distribution for samples of size 64 on a bell curve.

B. What is the probability that the average IQ, from a random sample of 64 individuals, is greater than 102?

C. What is the probability the average IQ, selected from a random sample of 64 individuals, is less than 94?
