I need help finding the margin of error in my statistics class.

Find the margin of error. 99% confidence interval; n=201; x-bar=395; s=46
A.12.2 B.10.3 C.15.7 D.13.5

99% confidence interval is
x-bar +/- Margin of error
Margin of error = z-score or critical value for 99% confidence * s / sqrt n
= 2.58 * 46 / sqrt 201
= 2.58 * 46 / 14.18
= 2.58 * 3.24
= 8.36

Therefore answer to the question is NONE of the choices
