6. A logistic regression model is developed to explore the quality of wine on several different variables. The explanation of variables can be found here. The rating of wine is ranged from 0 to 10. In this model, we consider the wine as good quality if the rating is more than six. Otherwise, we regard it as poor quality. Consider the following as the screenshot of R-studio analysis.

6.1. Write the logistic regression equation. Interpret the model.

6.2. What is the quality of the wine with the following characteristics?

• fixed acidity=7

• volatile acidity=0.3

• citric acid=0.4

• residual sugar=11

• chlorides=0.05

• free sulfur dioxide=37

• total sulfur dioxide=188

• density=0.99

• PH=3.2

• sulphates=0.44

• alcohol=11
