Car Company A: 35, 28, 35, 30, 31, 36, 35, 30
Car Company B: 29, 33, 40, 27, 34, 34, 34, 25
The following data sets represent the highway fuel efficiency in miles per gallon (mpg) of randomly selected cars from two car companies. Which company has cars that are more consistent in highway fuel efficiency?
Car Company A is more consistent, because the range of highway fuel efficiency of its cars is lower than that of Car Company B.
Car Company B is more consistent, because the range of highway fuel efficiency of its cars is lower than that of Car Company A.
Cars from both companies have equally consistent highway fuel efficiency.
Car Company A is more consistent, because the range of highway fuel efficiency of its cars is higher than that of Car Company B.

Car Company A is more consistent because the range of highway fuel efficiency of its cars is lower than that of Car Company B. The range is the difference between the highest and lowest values in a data set, and a smaller range indicates greater consistency. In this case, Company A has a range of 6 (36-30), while Company B has a range of 15 (40-25).
