**MathMate**, Sunday, September 6, 2009 at 5:28pmIt depends on what he taught in class, but I am guessing that what the problem was trying to illustrate is that arithmetic means are very sensitive to "wild" data, or erroneous data that are out of range. This is probably in preparation to the next topic, medians and mode.

What you have stated are mathematical facts and perhaps not considered as illuminating observations.
