You may need to use the appropriate appendix table or technology to answer this question.IQ scores (as measured by the Stanford-Binet intelligence test) in a certain country are normally distributed with a mean of 95 and a standard deviation of 11. Find the approximatenumber of people in the country (assuming a total population of 323,000,000) with an IQ higher than 122. (Round your answer to the nearest hundred thousand.)

Mean(µ) = 95Standard deviations (σ) = 11X ~ N (µ, σ )= N(95, 11)
