Data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 46 wines, a model was created using the percentages of aloohol to predict wine qualityY-0.337 +0.5635X,, where X, in the alcohol content (%) and Y, is the rated quality of the wine. For these data, Syx 0.9316, X 10.63, and h 0.027260 when X 10. Complete parta (a) throia. Construct a 05% confidence interval estimate of the mean wine quality rating for all wines that have 10% alcohol.4.988 spypx= 10 s 5.608(Type integers or decimals. Round to three decimal places as needed. Use ascending order)b. Construct a 95% prediction interval of the wine quality rating of an individual wine that has 10% alcohol.(Type integers or decimals. Round to three decimal places as needed. Use ascending order.)

The sample size is 46, regression equation is Y^=-0.337+0.5635X, SYX=0.9316, X¯=10.63, hi=0.027266.
