In an attempt to develop a model of wine quality as judged by wine experts, data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 12 wines, a model was created using the percentages of alcohol to predict wine quality. For those data, SSR = 19,546 and SST = 29,242. Use this information to complete parts (a) through (c) below. a. Determine the coefficient of determination, , and interpret its meaning. 2 = 0.668 (Round to three decimal places as needed.) Interpret the meaning of ?. It means that 66.8 % of the variation in wine quality can be explained by the variation in alcohol content. (Round to one decimal place as needed.) b. Determine the standard error of the estimate. Syx = (Round to four decimal places as needed.)
