standard deviation of women (σ)= 2.4 inches

mean of men (μ)=70 inches

standard deviation of women (σ)= 2.5 inches

for women

$P(x>66)$

$P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}$

$P(x>66) = 1-P( z$

$P(x>66) = 1-P( z$

using z-table

$P(x>66)= 1 - 0.8944$

$P(x>66)=0.1056[/tex]for men[tex]P(x>66)$

$P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}$

$P(x>66) = 1-P( z$

$P(x>66) = 1-P( z$
