Question

a study of the fuel economy for various automobiles plotted the fuel consumption vs speed. A least-squares regression line was fitted to the data and the residual plot is displayed below. what does the pattern of the residuals tell you about the linear model?

a) the residual plot clearly contradicts the linearity of the data
b) the evidence is inconclusive
c) the residual plot confirms the linearity of the data
d) the residual plot suggests a different line would be more appropriate
e) none of the above is accurate

Answer 1

Answer 2

There appears to be a pattern with the residuals, so i'd think
d) the residual plot suggests a different line would be more appropriate

i don't think it's enough to say a) the residual plot clearly contradicts the linearity of the data
