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=21,071 and SST=33,354. Use this information to complete parts?(a) through?(c) below.

a. Determine the coefficient of determination, r, and interpret its meaning. 2 = (Round to three decimal places as needed.) Interpret the meaning of r2 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. Syx =(Round to four decimal places as needed.) c. How useful do you think this regression model is for predicting wine quality? O A. It is not very useful for predicting wine quality because the coefficient of determination is close to 1. O B. It is very useful for predicting wine quality because the coefficient of determination is close to 1. O C. It is not very useful for predicting wine quality because the coefficient of determination is close to 0. O D. It is very useful for predicting wine quality because the coefficient of determination is close to 0
