Pennies made before 1983 are 97% copper and 3% zinc, whereas pennies made after 1983 are 3% copper and 97% zinc. Listed below are the weights (in grams) of pennies from each of the two time periods. Find the mean and median for each of the two samples, then compare the two sets of results. Before 1983: 3.1588 3.1276 3.0773 3.1039 3.1086 3.1045 After 1983: 2.4994 2.4826 2.4906 2.5028 2.4958 2.4847
