Question: IQ scores. The mean IQ for the entire population in any age group is supposed to be 100. Suppose the IQ scores of 31 seventh-grade girls in a Midwest school district are measured and the sample mean is found to be 105.8 and the sample standard deviation is 14.3. Treat the scores as if they were an SRS from all middle-school girls in this district. Do the scores provide good evidence that the mean IQ of this population is not 100?
