Compare the variation in the numbers of chocolate chips in Chips Ahoy (regular) cookies (listed in Table 3-1) and the weights of regular Coke listed in Data Set 19 of Appendix B. Using the sample data, we have these results: Cookies have
x = 24.0 chips and s = 2.6 chips; Coke has x = 0.81682 lb and s = 0.00751 lb. Note that we want to compare variation among numbers of chocolate chips to variation among weights of Coke.
