The production of wine is a multibillion-dollar worldwide industry. In an attempt to develop a model of wine quality as judged by wine experts, data collected from red wine variants of Portuguese “Vinho Verdeâ€� wine. A sample of 50 wines is stored in VinhoVerde. Develop a simple linear regression model to predict wine quality, measured on a scale from 0 (very bad) to 10 (excellent), based on alcohol content ( % ) . a. Construct a scatter plot . For these a data, b 0 = − 0.3529 and b 1 = 0.5624. b. Interpret the meaning of the slope, b 1 , in this problem. c. Predict the mean wine quality for wines with a 10 % alcohol content. d. What conclusion can you reach based on the result of a − c ?

Definition Definition Representation of the direction and degree of correlation in graphical form. The grouping of points that are plotted makes it a scatter diagram. A line can be drawn showing the relationship based on the direction of points and their distance from each other.
