Assume that IQ scores are normally distributed with mu = 100 and sigma = 15. If an individual is randomly selected find the probability that the y will have an IQ score above 130. What is the probability the ir IQ score will be between 85 and 115? Find the 99th percentile of IQ scores (find the IQ score such that 99% of the population has an IQ less than or equal to that score) Solution a)0.0228 b)0.6826 c)134.95.
