an attempt to develop a model of wine quality as judged by wine experts, data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 12wines, a model was created using the percentages of alcohol to predict wine quality. For those data, SR=18,671 and SST=27,382.Use this information to complete parts (a) through (c) below. Please complete part 3(B) ONLY.
Question content area bottom
Part 1
a. Determine the coefficient of determination,
r2,
and interpret its meaning.
r2=0.682
(Round to three decimal places as needed.)
Part 2
Interpret the meaning of r2.
It means that
68.2
of the variation in
wine quality
can be explained by the variation in
alcohol content.
(Round to one decimal place as needed.)
Part 3
b. Determine the standard error of the estimate.
SYX=
(Round to four decimal places as needed.)
