interviews a mathematician, a statistician and an accountant and gives them all a problem as part of the interview process.
Each answers the problem in his own way.
The mathematician: Well, the limit from both the left and the right is the number 3.
The statistician: I'm 95% confident that the correct answer is 3.
The accountant: At first blush, it looks like 3, but, really....what do you want the answer to be?
