Question
The fuel efficiencies of 2007 models of midsized automobiles were studied..
The fuel efficiencies of 2007 models of midsized automobiles were studied, and the side-by-side boxplots of the distribution of the miles per gallon in city driving (MPG-City) for automobiles manufactured in North America, Asia, and Europe are given below. From these boxplots we can see that Option IV: the overall variability in fuel efficiency rating is highest for European-built automobiles. Options I, II, and III are correct. Option III the median fuel efficiency rating is highest for automobiles manufactured in Asia. Option I: the MPG-City for 75% of automobiles from Asia is higher than the MPG-City for 75% of European automobiles. Option II: 75% of the cars from Asia have higher fuel efficiency than 50% of the cars from North America. all of the above are correct.Explanation / Answer
Ans:
Options I,II,III are correct.
Option IV is incorrect,as overall variability is highest for asian built automobiles,as IQR(nterquartile range) is highest for Asian,which indicates highest variability.
