For 100 randomly-selected moderately priced wines, a number of variables are recorded, including: Quality Rating (1-10, 10 is best), Alcohol Content (%. For example, 12% is recorded as 12 in the dataset), Producer (California, France, or Italy). and whether or not the wine was considered a Vintage (0-No. 1-Yes). Below is the regression output for the model: Quality Rating vs. Alcohol Content, Producer, and Vintage.
