The production of wine is a multibilion-dollar worldwide industry, In an attempt to develop a model of wine quality as judged by wine experts, data was collected from red wine variants of a certain type of wine. A sample of 12 wines is given. 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 (\%) Complete parts (a) through (d) below 囲 Click the icon to view the data of wine quality and alcohol content. a. Construct a scatter plot Choose the correct graph below. b. For these data, b0=50b_{0}=50 and b1=0.2b_{1}=0.2 Interpret the meaning of the slope, b1b_{1}, in this problem Choose the correct answer below A. The slope, b1b_{1}, implies that for each increase of alcohol percentage of 10 , the wine quality rating is expected to increase by the value of b1b_{1}
O B. The slope, b1\mathrm{b}_{1}, implies that for each 0.2 percentage decrease in alcohol content, the wine should have an increase in its rating by 1 . OCO C. The slope, b1\mathrm{b}_{1}, implies that the alcohol content is equal to the value of b1b_{1}, in percentages. O. The slope, b1b_{1}, implies that for each increase of 1 wine quality rating, the alcohol content is expected to increase by the value of b1b_{1}, in percentages. c. Predict the mean wine quality for wines with an 12%12 \% alcohol content (Round to two decimal places as needed) solve this View an example Get more help - Clear all Check answer

Studdy Solution
Calculate the value:
y=50+2.4=52.4 y = 50 + 2.4 = 52.4
The predicted mean wine quality for wines with a 12% 12\% alcohol content is:
52.4 \boxed{52.4}
