A population has parameters $\displaystyle \mu={85.1}$ and $\displaystyle \sigma={54}$. You intend to draw a random sample of size $\displaystyle {n}={220}$.

What is the mean of the distribution of sample means?
$\displaystyle \mu_{{\overline{{x}}}}=$

What is the standard deviation of the distribution of sample means?
(Report answer accurate to 2 decimal places.)
$\displaystyle \sigma_{{\overline{{x}}}}=$
