Data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 50 wines, a model was created using the percentages of alcohol to predict wine quality. The data are modeled by Yi=−0.384+0.5332Xi, where Xi is the alcohol content (%) and Yi is the rated quality of the wine. For these data, SYX=0.9431, X=10.19, and hi=0.029612 when X=11. a.
