Question: Some IQ scores are standardized with a mean of 100 and a standard deviation of 20. Using the 68-95-99.7 Rule.Determine
What percent of people would have an IQ score of 100 or above.  Edit

Answer: The 68-95-99.7 Rule is also known as the Empirical Rule. The Empirical Rule Theorem states that: - 68% of the observations lie within one standard deviation of the mean. - 95% of the observations lie within two standard deviations of the mean. - 99.7% of the observations lie within three standard deviations of the mean. The mean score is 100. This means half of the scores fall above the mean and half fall below the mean Answer: 50%.  Edit
