Quizplus · Accepted Answer

Given the complexity of calculating the multiple regression equation, $R^2$, adjusted $R^2$, and the P-value manually, these values are typically obtained using statistical software. The correct choice indicates the highest $R^2$ and adjusted $R^2$ values, suggesting a strong relationship between the dependent variable (CO) and the independent variables (TAR and NIC), with a P-value of 0.000 indicating that the relationship is statistically significant.
