Explanation:

The z - score formula is $z=\frac{x - \mu}{\sigma}$, where $x$ is the data - value, $\mu$ is the mean and $\sigma$ is the standard deviation. When $x<\mu$, then $x - \mu<0$. Since $\sigma>0$, the value of $z=\frac{x - \mu}{\sigma}<0$.

Answer:

the corresponding z - score is negative.
