Interpret the value 28.2 in context 28.2 is the average number of calories in a 12-ounce can of American beer. 28.2% of the variation in calories can be explained by the alcohol content of a 12-ounce can of American beer. 28.2 is the slope of the regression line. For every increase of one percentage in alcohol content, we would expect an additional 28.2 calories in a 12-ounce can of American beer. Page Page 23 of 4

Transcribed Image Text:Listen
In a study of American beers, a researcher computed the least-squares regression line of
calories (per 12-ounce can) against alcohol content (as a %), obtaining the following
equation:
Calories= 8.25 + 28.2 x Alcohol Content
Interpret the value 28.2 in context
28.2 is the average number of calories in a 12-ounce can of American beer.
28.2% of the variation in calories can be explained by the alcohol content of a 12-ounce
can of American beer.
28.2 is the slope of the regression line.
For every increase of one percentage in alcohol content, we would expect an additional
28.2 calories in a 12-ounce can of American beer.
