Foofy conducts an experiment in which participants are given 1, 2, 3, 4, 5, or 6 hours of training on a new computer statistics program. They are then tested on the speed with which they can complete several analyses. She summarizes her results by computing that the mean number of training hours per participant is 3.5, and so she expects ^ would also be 3.5. Is she correct? If not, what should she do?
