The Standard Error \(\sigma_e\) is given by
\begin{equation*}
\sigma_e = \frac{s}{\sqrt{n}}
\end{equation*}
where s is the standard deviation of the sample. For this presentation, we will assume that the actual population is relatively large relative to the sample size. In cases where this is not true, an adjustment (not presented here) will need to be made when computing \(\sigma_e\text{.}\)
