"""This program generates a normal probability plot for the distribution
of running speeds in a road race.
The results suggest that the distribution is bimodal, with a small
number of fast runners who seem to belong to a different normal
distribution.
I conjecture that these are people who have trained at a competitive
level. Among them, the distribution is normal, but there is a gap
between them and the rest of the population.
