Use the PewKids dataset to run two regression models, both using family income as the dependent variable. In the fi rst, use the fi ve race reference-group variables. In the second, use the race (white/ nonwhite) dichotomy. After interpreting your results, address these questions: Which slopes in the fi rst model are closer in value to the slope in the second model? Why do you think this happened?
