According to the United States Health and Human Services, the mean height for Americans is 1.757 meters for men and 1.618 meters
Alchen [17]

Answer:

Her z-score is 2.03.

Step-by-step explanation:

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

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

Michelle’s height is 1.758 meters. What is her z-score?

Michelle's is a woman.

The average height of women is \mu = 1.618 and the standard deviation is \sigma = 0.069

This is Z when X = 1.758. So

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

Z = \frac{1.758 - 1.618}{0.069}

Z = 2.03

Her z-score is 2.03.
