I 15. IQ and Lead Exposure Standard IQ tests are designed to yield a population mean of 100. Data Set 11 "IQ and Lead" in Appendix B includes IQ scores of 21 children with high expo- sure to lead. For this group, the IQ scores have a mean of 86.90476 and a standard deviation of 8.988352. Use a 0.05 significance level to test the claim that this sample is from a population with mean IQ equal to 100. Do the results prove that exposure to lead has an adverse effect on IQ scores of children? Doto Fot 3? "Taxis" from Appendix B,
