Explanation:
Detailed explanation-1: -The acceptable margin of error usually falls between 4% and 8% at the 95% confidence level.
Detailed explanation-2: -Percent error would be a more appropriate measure of accuracy. Percent error compares the theoretical value of a quantity with its measured value. Note that precision only compares between multiple measurements so a percent error may be less appropriate in that case.
