Concept explainers
Does Weight Change with Age? Refer to Data Set 1 “Body Data” in Appendix B and use the weights of males partitioned into the three different age brackets of 18-25, 26-40, and 41-80. Test the claim that men in those three age brackets have the same mean weight.
Sorting One challenge in this project is identifying the weights of men in the three age brackets. First, use the sort feature of your technology to sort all of the columns using Gender as the basis for sorting. You can then delete all of the rows representing females. Next, sort all of the columns using Age as the basis for sorting. It will then be much easier to identify the weights in the different age brackets.
