Part E: Is this model the best fit for the data?
Explain your reasoning. If a transformation is
required, what is the equation for the new model?
Show your work. (5 points)
Part F: Using the transformation you gave in Part E,
what would be the new estimate for fuel efficiency
of the vehicle weighing 2,684 pounds? What effect
did this new model have on the residual, compared
to the result you found in Part C? Show all work. (5
