Note: standard Normal Curve: µ = 0 and σ =1
for ex: to the right of center, z-score becomes larger as distance, in terms of σ from the mean, increases.
Men Normal Distribution: µ = 69.2 and σ = 2.65
Women Normal Distribution: µ = 64.3 and σ = 2.59
z(man 75") = ( 75 - 69.2)/2.65 = 2.1887
z(woman 71") = (71 - 64.3)/2.59 = 2.5869****Represents More standard deviations from mean
c) Who is 'relatively taller?
-The 5 foot 11 inch American woman
