On standard IQ tests, the mean is 120 and the standard deviation is 15. The results are very close to fitting a normal curve. Suppose an IQ test is given to a very large group of people. Find the percent of people whose IQ score is less than 120.

    If the mean is 120, remember that the mean divides a distribution in half. 50% is below the mean and 50% is above the mean.
