ny: this is a designed as a really easy question to o test your
understanding of different "averages", whichever are discussed in
your textbook: mean (that is arithmetic average), median,
apparently, midrange, whatever else (see your textbook). but keep in
mind that mode is the value that is encountered most often, so you
can't say 30.6 is the mode as you only see it once as any other
number in the row.
With the limited information you gave, it's
impossible to say which value makes car A the best, as we don't know
what those numbers mean - if it's better to be higher or lower, and
higher/lower than what (what are the numbers for other cars). you
should read what those numbers mean and what are the numbers for
other cars. what you need to do is calculate the mean, the median,
etc. and see using which one makes car 1 seem better (which is all
there is to the "substantiate")
