If mathematical ability in the general population is N(mu, sigma[SUP]2[/SUP]), he would have been at least mu + eight*sigma.
Note to Self
Stop embarrassing myself by trying to do calculations in my head.
It would take only 5.15 standard deviations from the mean to be in the top 1,000 out of a population of 7.5 billion.
