I completed Math 30 Pure last semester and I've never learned anything you posted above, that must be college/university level statistics.
From the way the question was worded, as a grade 12 student, I would assume that it would be just asking about how one can manipulate the mean and the standard deviation. Throwing out or adding data points may not be a valid method for stats but in grade 12 math, I'm pretty sure they're just testing you if you know what a mean or standard deviation is.

Fair enough, I may be too far removed to give good advice. But it really is the right way of doing it...
