Larger Data Sets. In Exercises 17–24, use the indicated Data Sets in Appendix B. The complete data sets can be found at www.TriolaStats.com. Assume that the paired sample data are simple random samples and the differences have a distribution that is approximately normal.
22. Heights of Fathers and Sons Repeat Exercise 10 “Heights of Fathers and Sons” using all of the heights of fathers and sons listed in Data Set 5 “Family Heights” in Appendix B.
10. Heights of Fathers and Sons Listed below are heights (in.) of fathers and their first sons. The data are from a journal kept by Francis Gallon. (See Data Set 5 “Family Heights” in Appendix B.) Use a 0.05 significance level to test the claim that there is no difference in heights between fathers and their first sons.
