- Assuming the IQ scores of a distribution of 8,000 college-aged students is bell-shaped with a mean of 120 and a standard deviation of 8. Using the Empirical Rule, deter- mine the approximate percentage and number of students who are expected to have IQ scores from: a) 104 to 136. b) 112 to 128. c) 112 to 136. d) 104 to 144. e) Would you interpret an IQ score of 150 to be an unusual IQ or a typical IQ? Explain. f) Would you interpret an IQ score of 90 to be a potential outlier? Explain. - Assuming the IQ scores of a distribution of 8,000 college-aged students is bell-shaped with a mean of 120 and a standard deviation of 8.
