A simple random sample of size $36$ is drawn from from a normally distributed population with a mean of $\mu = 80$ and a standard deviation of $\sigma = 6$ .

Determine the expected value of the sample mean, $\mu_{\bar{X}}$ , and the standard error of the sample mean, $\sigma_{\bar{X}}$ .

$\mu_{\bar{X}} =$

$\sigma_{\bar{X}} =$
