Assignment 8 - Polynomial Regression, Validation, and Categorical Predictors 1. The file NCbirths.jmp contains data on a sample of 150 birth records that statistician John Holcomb selected from the North Carolina Stat Center for Health and Enviromental Statistics. One of the questions if interest is how the birth weights (in ounces) of the babies might be related to the mother's race. The variable MonRace codes the mother's race as white, black, Hispanic, or other. We set up indicator variables for the last three categories. Here is the fitted model: Birth Weight; =117.87-7.31*I Race; =6\\+.65*I Race = Hispanic -0.73*I (Race;= other) Explain what each of the coefficients in this fitted model tells us about race and birth weights for babies born in North Carolina
