Question

Jayce Dougherty · Accepted Answer

Final Answer : A, Explanation :  To compute a margin of error, we need to know the sample size, the standard deviation, and the z-score for the desired confidence level. Only option A includes all three of these necessary components. The sample mean and median are important measures of central tendency in statistics, but they are not directly used in calculating a margin of error.
