In the multiple logistic regression of wine quality on the physio-chemical predictors, the coefficient estimate of 0.7823 for alcohol means

• The probability of good wine quality is higher on average for higher alcohol percent, holding the other physio-chemical predictors fixed.
• The correlation between wine quality and alcohol percent is 0.7823.
• For each additional percent of alcohol increase in wine, the probability of wine quality increases by 0.7823.
• The probability of good wine quality is higher on average for higher alcohol percent.
