Re TY:
sd= sqrt%28p%281-p%29n%29 = sqrt%28.09%2A.91%2A500%29 0r = sqrt%28.91%2A45%29 as 45 had been already determined.
p = .09, m = .09%2A500 = 45, sd = sqrt%28.91%2A45%29 = 6.4
45 ± 2•6.4 usual occurrences 23 to 58
would it be unusual to find 65 who cannot distinguish between the colors red and green? Yes
