Data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 48 ​wines, a model was created using the percentages of alcohol to predict wine quality. The data are modeled by Yi=−0.357+0.5392Xi​, where Xi is the alcohol content​ (%) and Yi is the rated quality of the wine. For these​ data,SYX=0.9852​,X=10.31​,and hi=0.095564 when X=8.
