$y = 10x + 30\\\y= mx+c$

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.
