Heights of Parents Data Set 2 in Appendix B includes the heights of parents of 20 males. If the difference in height for each set of parents is found by subtracting the mother’s height from the father’s height, the result is a list of 20 values with a mean of 4.4 in. and a standard deviation of 4.2 in. Use a 0.01 significance level to test the claim that the mean difference is greater than 0. Do the results support a sociologist’s claim that women tend to marry men who are taller than themselves?
