Weights of Quarters
Use the frequency distribution from Exercise 28 in Section 2-2 to construct a histogram. Compare this histogram to the histogram from Exercise 19.



Exercise 28:



Weights of Quarters
Refer to Data Set 20 in Appendix B and use the weights (grams) of the post-1964 quarters. Construct a frequency distribution. Begin with a lower class limit of 5.5000 g, and use a class width of 0.0500 g. Compare the frequency distribution to the result from Exercise 27.



Exercise 19



Weights of Quarters
Use the frequency distribution from Exercise 27 in Section 2-2 to construct a histogram.



Exercise 27:



Weights of Quarters
Refer to Data Set 20 in Appendix B and use the weights (grams) of the pre-1964 quarters. Construct a frequency distribution. Begin with a lower class limit of 6.0000 g, and use a class width of 0.0500 g.



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.
