Real cute. The median, mode, average and everything else is all clustered. Terrific looking bell curve.

Well, I was being serious. If you have three distributions (one for each race) that have separate means, one can't say much at all unless one also knows the three variances.

Once one has the population means and variances, then one can specify the minimum sample size needed to make statements of a given confidence about outcomes.

Basic statistics.
