Step 1

1 of 3Recall: A test statistic measures the difference between a given sample mean $\overline{x}$ and a benchmark $\mu_{0}$ in terms of the standard error of the mean.

$z_{calc}=\frac{\bar x-\mu_{0}}{\sigma_{\bar x}}=\frac{\bar x-\mu_{0}}{\sigma/\sqrt{n}}$

($\sigma_{\bar x}=\sigma/\sqrt{n}$ is the standard error of the sample mean)
