Use the lung function data described in Appendix A. For the parents we wish to relate Y = weight to X = height for both men and women in a single equation. Using dummy variables, write an equation for this purpose, including an interaction term. Interpret the parameters. Run a regression analysis, and test whether the rate of change of weight versus height is the same for men and women. Interpret the results with the aid of appropriate graphs.
