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 residuals plot,do you think that this linear model is appropriate?
A)Yes,residuals show no pattern.
B)Yes,residuals show a linear pattern.
C)No,residuals show a curved pattern.
D)No,residuals show no pattern.
E)Yes,residuals show a curved pattern.
