5. In Problem #4 of the first homework assignment you analyzed data on the DDT concentrations in catfish caught in the Tennessee River basin. In addition to measuring the DDT concentration, the researchers measured the length and weight of the fish that were caught. Create a histogram of the weight data, using intervals (bins) of 0-200 g, 200-400 g, 400-600 g, ... , 1600-1800 g.
