Intelligence quotients (IQ scores) are normally distributed with a mean of 100 and a standard deviation of 15. An individual is selected at random, determine the probability that the individual has IQ scores. a) Exactly 130  b) People who score in the top 2.5% of the distribution of scores are considered geniuses. What is the minimum score one needs to obtain in order to be considered a genius?  c) People who score in the bottom 10% of the distribution of scores often needs re-testing. What is the highest score one could achieve and still needs to be retested?
