A Fortune 500 company was interviewing for a CFO, and narrowed the field down to 4 candidates - a mathematician, a market researcher, a statistician, and an economist. Because they were so close in every other respect, they brought all 4 in together for an executive panel interview.

The CEO asked the interviewees "What's 2+2"?

The mathematician replied "Four".

The market researcher said "Ha! I heard you asked the tricky questions! So..." - and here he rustled through the pile of paperwork he'd brought with him - "...yesterday I surveyed 100 second grade teachers, and the most common answers ranged between 3 and 5".

The statistician looked sideways at the columns of figures in front of the market reseacher, spent a few minutes jotting on a napkin, and said "I can state with 95% confidence the answer is four".

The economist glanced at the rest of the candidates with barely-disguised pity, leaned over the desk, and whispered in the CEO's ear...

"What would you like it to be?"
