what is the formula for margin of error?\no $me = \\frac{z\\cdot\\sqrt{s}}{\\sqrt{n}}$\no $me =…

Brief Explanations:

The formula for the margin of error (ME) for a confidence - interval when the population standard deviation $\sigma$ is unknown (and we use the sample standard deviation $s$ instead) in a large - sample or normal - population with known degrees of freedom situation is $ME=\frac{z\cdot s}{\sqrt{n}}$, where $z$ is the z - score corresponding to the desired level of confidence, $s$ is the sample standard deviation, and $n$ is the sample size.

Answer:

C. $ME = \frac{z\cdot s}{\sqrt{n}}$
