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: 35,28,35,30,31,36,35,30
Car Company B: 29,33,40,27,34,34,34,25
A. Car Company A is more consistent, because the range of highway fuel efficiency of its cars is higher than that of Car Company B.
B. Cars from companies have equally consistent highway fuel efficiency.
C. Car Company A is more consistent, because the range of highway fuel efficiency of its cars is lower than that of Car Company B.
D. Car Company B is more consistent because the range of highway fuel efficiency of its cars is lower than that of Car Company A.
C. Car Company A is more consistent, because the range of highway fuel efficiency of its cars is lower than that of Car Company B.
In this case, the range of Car Company A is 8 (36-28) and the range of Car Company B is 15 (40-25). A smaller range indicates that the values in the data set are closer together, making it more consistent.
