When designing
an environment, one common criterion is to use a design that accommodates 99%
of the population. How high should doorways be it 99% of men will fit through
without bending or bumping their head? That is, find the 99th percentile of
heights of men. Heights of men are normally distributed with a mean of 70 inch,
and a standard deviation of 2 inch. Choose the best answer.
