One of the tallest living men has a height of 236 cm. One of the tallest living women is 224 cm tall. Heights of men have a mean
Roman55 [17]

Answer:

A. The woman is relatively taller because the z score for her height is greater than the z score for the man​'s height.

Step-by-step explanation:

Whoever has the highest z-score, is taller relative to the population of the same gender.

The z-score of a value X in a set with mean \mu and standard deviation /sigma is given by:

Z = \frac{X - \mu}{\sigma}

Solution:

Heights of men have a mean of 170 cm and a standard deviation of 6 cm. One of the tallest living men has a height of 236 cm. So the z-score of his height is:

Z = \frac{X - \mu}{\sigma} = \frac{236-170}{6} = 11

Heights of women have a mean of 161 cm and a standard deviation of 5 cm.

One of the tallest living women is 224 cm tall. The z-score of the women's height is

Z = \frac{X - \mu}{\sigma} = \frac{224-161}{5} = 12.6

The women has a higher z-score, so she is relatively taller.

The correct answer is A
