From the family lung function data set in Appendix A, perform a regression analysis of weight on height for fathers. Repeat for mothers. Determine the correlation coefficient and the regression equation for fathers and mothers. Test that the coefficients are significantly different from zero for both sexes. Also, find the standardized regression equation and report it. Would you suggest removing the woman who weighs 267 pounds from the data set? Discuss why the correlation for fathers appears higher than that for mothers.
