What bothers me is that no one, not the coach nor any of the posters here, clarified the situation by noting that while the average speed of a black person is only very slightly faster than a white person, the nature of the normal distribution means that at the extreme tails, where elite athletes appear, the effect is exggerated far beyond what it is in the general populaion. (In other words while you might only be able to lay 6-5 that a random black guy can beat a random white guy, you might be able to lay 4-1 if there is no bet unless one of them breaks 9.5 for a hundred yards.)

This is a good point, maybe it can save this guy's job. [img]/images/graemlins/tongue.gif[/img] I looked at the ratio in the tails for a 5% difference in the means, and it was about 3-1.
