(Case Study) A group of children who lived near a lead smelter in El Paso, Texas, were identified and their blood levels of lead were measured. An exposed group of 80 children were identified who had blood-lead levels 2 40 µg/mL in 1972-1973, and it was identified as group 2. A control group of 112 children were also identified who had blood-lead levels < 40 ug / mL in 1972-1973, and was identified as group-1. For both groups, the number of finger-wrist taps in the dominant hands (MAXFWT) for the both groups are displayed with a box plot as shown below: 80 70 55 49 49 40 Group-1 Group-2 How many the dominant hands between 49 and 70? children in the control group have the number of finger-wrist taps in MAKEWT
