A fine red wine Camille manages a winery that is known for its fine red wine of the “Vinho Verde” variant. Wine-tasting experts, or sommeliers, come every year to rate the wine quality of each of her wines using a numerical score that ranges from 1 (low quality) to 7 (high quality). To improve her understanding of the sommeliers’ wine rating system, Camille collected data by hiring scientists to take physicochemical tests on each of her wines. Using the scientific data, she runs a regression of wine quality on the amount of fixed acidity, residual sugar, density, and alcohol content. Below is her R regression output.
