Question

The margin of error can be determined if you know only the confidence level, population standard deviation, and sample size.

Short answer

The given statement is True.

Step-by-step solution

Given Information

Confidence level, population standard deviation and sample size is known to us.

Explanation

Mathematically, margin of error is calculated as:

$E=z_{\frac{\alpha }{2}}\left(\frac{\sigma }{\sqrt{n}}\right)$

$\sigma$is population standard deviation.

$n$ is sample size.

Hence, the given statement is True.
