sample mean. Show the complete calculation steps.

And by the way, let's hope this incident taught the students involved something about keeping records carefully and in a permanent fashion, with back-up of the data. If they didn't learn that, they will "probably" soon become "statistics" in the business world, if you catch my drift .... -- Cheers, --Mr. d.
