Solution-Weights and fuel efficiencies

Weights and fuel efficiencies

Reference no: EM132514719

For the following problem, suppose we have a collection of cars, we measure their weights and fuel efficiencies, and generate the following graph of the data. (Source:https://lib.stat.cmu.edu/DASL/Datafiles/carmpgdat.html)

What can we conclude from this data?

A) The strong association proves that more weight causes a lower mpg rating.

B) Higher vehicle weights are strongly associated with lower MPG rates, but this data set does not indicate that higher vehicle weights cause lower MPG.

C) It makes sense that more gas is required to move heavier vehicles, so heavier cars cause lower MPG.

D) This data shows that to lower MPG and increase fuel efficiency, engineers need to design lightweight vehicles.
