Vincent and Peter are sales associates and are up for promotion to sales manager.

In an assessment center that was meant to stimulate the job of sales manager, on a 1 = very poor to 10 = outstanding scale, Vincent's average score was 8.2 and Peter's was 9.2. Other things being equal, who should be promoted? Why?
