Question: Use the same scale to construct boxplots for the weights of the pre-1964 silver quarters and the post-1964 quarters from Data Set 20 in Appendix

Use the same scale to construct boxplots for the weights of the pre-1964 silver quarters and the post-1964 quarters from Data Set 20 in Appendix B. Use the boxplots to compare the two data sets.

Data Set 20: Coin Weights (grams) The "pre-1983 pennies" were made after

Data Set 20: Coin Weights (grams) The "pre-1983 pennies" were made after the Indian and wheat pennies, and they are 97% copper and 3% zinc. The "post-1983 pennies" are 3% copper and 97% zinc. The pre-1964 silver quarters" are 90% silver and 10% copper. The post-1964 quarters" are made with a copper-nickel alloy. STATDISK: Data set name is Coins. Minitab: Worksheet name is COINS.MTW. Excel: Workbook name is COINS.XLS. TI-83/84 Plus: App name is COINS, and the file names are the same as for text files.
