Use the next formula to find the margin or error:

$MOE=z*\frac{\sigma}{\sqrt{n}}$

z is the critical value (For a 95% confidence level the z-score is 1.95998)

σ is the standard deviation

n is the sample size

$\begin{gathered} MOE=1.95998*\frac{20.4}{\sqrt{36}} \\ \\ MOE\approx6.6639 \end{gathered}$ <h2>Then the margin of error is: 6.6639</h2> $\begin{gathered} \bar{x}\pm MOE \\ \\ 38.6\pm6.6639 \end{gathered}$
