Suppose IQ scores are normally distributed with mean 100 and standard deviation 10. Which of the following is false? Group of answer choices A normal probability plot of IQ scores of a random sample of 1,000 people should show a straight line. Roughly 68% of people have IQ scores between 90 and 110. An IQ score of 80 is more unusual than an IQ score of 120. An IQ score greater than 130 is highly unlikely, but not impossible.
