a. Determine the coefficient of determination, $r^2$, and interpret its meaning. $r^2=$ (Round to three decimal places as needed.) Interpret the meaning of $r^2$. It means that $\%$ of the variation in can be explained by the variation in (Round to one decimal place as needed.) b. Determine the standard error of the estimate. $S_{YX}=$ (Round to four decimal places as needed.) c. How useful do you think this regression model is for predicting wine quality? A. It is not very useful for predicting wine quality because the coefficient of determination is close to 1 . B. It is very useful for predicting wine quality because the coefficient of determination is close to 1 . C. It is very useful for predicting wine quality because the coefficient of determination is close to 0 . D. It is not very useful for predicting wine quality because the coefficient of determination is close to 0 .
