Question: Refer to Original Source 20 on the CD, "Organophosphorus pesticide exposure of urban and suburban preschool children with organic and conventional diets." In Table 4 on page 381, information is presented for estimated dose levels of various pesticides for children who eat organic versus conventional produce. Find the data for malathion. Assume the minimum exposure for both groups is 0. Otherwise, all of the information you need for a five-number summary is provided. (Note that the percentiles are the values with that percent of the data at or below the value. For instance, the median is the 50th percentile.)
