Remember that we already learned about the standard error .... The standard error of the sample mean is given by the following equation: $$\sigma_\bar{y} = \frac{\sigma}{\sqrt{n}} $$. In the above equation, $\sigma$ is the population standard deviation. But like $\mu$, $\sigma$ is an unknown parameter.
