question 39

Multiple Choice

One of the important factors determining a car's fuel efficiency is its weight.This relationship is examined for 11 cars,and the association is shown in the scatterplot below.
If a linear model is considered,the regression analysis is as follows:
Dependent variable: MPG
R-squared = 84.7%
VARIABLE COEFFICIENT
Intercept 47.1181
Weight -7.34614
The residuals plot is:
Based upon the information above,what re-expression of Y would be appropriate?

• A)log y gallons per mile
• B)100 ∙ Gallons per 100 miles
• C)-100 ∙ Gallons per 100 miles
• D)100 ∙ Gallons per 100 miles
• E)100 ∙ Gallons per 100 miles
