Suppose that the mean IQ in the United States is roughly100 and the standard deviation is 15 points. People withIQs of 145 or higher are considered “geniuses” on somescales of measurement. What percentage of the population is expected to have an IQ of 145 or higher? In a country with 300 million people, how many geniuses arethere expected to be?
