A set of test scores are normally distributed. The mean is 100 and the standard deviation is 20. These scores are converted to s

Whitepunk [10]

Answer:

The z-scores of both the mean and the median are zero.

Step-by-step explanation:

In a normal distribution, the mean and median values will be the same, in this case, 100. Therefore, both the mean and median will have the same score.

The z-score is given by:

$z=\frac{X-\mu}{\sigma}$

For X = 100:

$z=\frac{100-100}{20}\\ z=0$

The z-scores of both the mean and the median are zero.
