A survey found that women's heights are normally distributed with mean 63.7 in. and standard deviation 2.4 in. The survey also

Answer:

The percentage of men meeting the height requierements is 11.47%.

As women have a less mean height, closer to the height requierments than men's mean height, it is expected that more percentage of women will fall within the height requirements.

Step-by-step explanation:

We have men's height normally distributed with mean 67.4 in and standard deviation 3.7 in.

The amusement park requires heights between 57 in and 63 in.

We can calculate the proportion using the z-scores and the standard normal probability distribution.

$z_1=\dfrac{X_1-\mu}{\sigma}=\dfrac{57-67.4}{3.7}=\dfrac{-10.4}{3.7}=-2.811\\\\\\z=\dfrac{X-\mu}{\sigma}=\dfrac{63-67.4}{3.7}=\dfrac{-4.4}{3.7}=-1.189$
