A study was conducted to examine the association between lead exposureand developmental features in children. The excel file containing the data on 99 children is called LEAD_MAXFWT.xlsx and is located in the Data Sets folder under Contents in A2L. Children were divided into two lead exposure groups: group 1 (GROUP=1, n=64) were children who lived less than 25 km away from a lead smelter, and group 2 (GROUP=2, n=35) were children who lived more than 25 km away from a lead smelter. One important outcome measure that was captured was Weschler IQ score (IQF). Use these data to answer the questions below. a.    Create one box and whisker plot comparing the distribution of the IQF scores for the two groups of children. Does there appear to be a significant difference between IQ scores for the two groups? Health Science Science Nursing HTH SCI 2S03 Share QuestionEmailCopy link Comments (0)
