Re: Each employee on a certain task force is either a manager
Ron, how do you know that the average is a weighted average in this case? The problem states "average" and I believe the reciprocity formula works for weighted average? Help, please!! I'm taking my test on Monday. Thanks so much!!

any time you have N number of one thing and M number of another thing, and you take the average, that's a "weighted average".
what is a "reciprocity formula"?
