Review: Comparing Mean and Median
Explanation
We can exhaustively enumerate what we are talking about
here: the first 8 positive multiples of 6 greater than 6 are: {12, 18, 24, 30,
36, 42, 48, 54}. Their median is the average of the middle two, so it's 33. And
moving out from 30 and 36, the numbers are evenly spaced from 33 in pairs. For
example, ,
and ,
so the first and the last cancel in pulling the average "left" or "right" of
33. Therefore, the median and the mean are both 33, and the ratio of one to the
other is 1.
The correct answer is (B).
