In Problem 13.4 on page 493, you used the percentage of alcohol to predict wine quality. The data are stored in VinhoVerde. For these data, S Y X = 0.9369 and h i = 0.024934 X = 10. a. Construct a 95 % confidence interval estimate of the mean wine quality rating for all wings that have 10 % alcohol. b. Construct a 95 % prediction interval of the wine quality rating of an individual wine that has 10 % alcohol. c. Explain the difference in the result in (a) and (b),

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
