Assume that IQ scores are normally distributed, with a standard deviation of 14 points and a mean of 100 points. If 145 people are chosen at random, what is the probability that the sample mean of IQ scores will not differ from the population mean by more than 2 points? (Round your answer to four decimal places.)
