Below Are Two Sets of Nested Models Using GSS2006 Data

Below are two sets of nested models using GSS2006 data. The first set includes only white women, the second set includes only black women.
Dependent Variable: Respondent's Income in Thousands of Dollars
$\begin{array}{c}\quad\quad\quad\quad\quad\quad\quad\text { White Women } \quad\quad \text { Black Women }\\\begin{array}{lcccc} & \text { Model 1 } & \text { Model } 2 & \text { Model } 1 & \text { Model } 2 \\\text { Yrs. of Educ. } & 3.14^{* * *} & -1.72 & 6.12^{* * *} & -15.25^{* * *} \\\text { Educ. Squared } & -- & .18^{* *} & -- & .78^{* * *} \\\text { Constant } & -12.78 & 19.16 & -54.12 & 88.75 \\\text { R-Squared } & .10 & .11 & .31 & .43 \\\mathrm{n} & 947 & 947 & 216 & 216\end{array}\end{array}$ By describing key differences between the effects for white and black women, address this question: for which group is there a more pronounced non-linear relationship?
