Answer:
A. ![Z=2.06](https://tex.z-dn.net/?f=Z%3D2.06)
Step-by-step explanation:
We want to find the Z-score of
if the population mean is
,and the population standard deviation is
.
We use the formula:
![Z=\frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
We substitute the values to obtain:
![Z=\frac{27-20}{3.4}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B27-20%7D%7B3.4%7D)
![Z=\frac{7}{3.4}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B7%7D%7B3.4%7D)
![Z=2.06](https://tex.z-dn.net/?f=Z%3D2.06)
The correct answer is A.
