The z-score is given by:
Z-score=(x-μ)/σ
where:
μ=mean
σ=std deviation
From the information:
mean for 20-29 year old man is μ=69.669 and std deviation is σ=3.23
mean for 20-29 year old woman is μ=64.564 and the std deviation is σ=3.83
the z-score for 75 inch men is:
z-man=(75-69.669)/3.23=1.651
the z-core for 70 inch woman:
z-woman=(70-64.564)/3.83
=1.42
From the above we conclude that the z-score for the man is relatively larger than that of the women, this means that the man is taller.
