h companies have the same mean highway fuel efficiency of 32.5 mpg. However, Car Company B has a smaller range (15 mpg) compared to Car Company A (8 mpg), indicating that their cars have more consistent highway fuel efficiency. Additionally, the standard deviation of Car Company B's data set (4.29 mpg) is smaller than that of Car Company A (2.48 mpg), further supporting the conclusion that Car Company B has cars that are more consistent in highway fuel efficiency. Therefore, Car Company B has cars that are more consistent in highway fuel efficiency.
