Answer
$\mu_{\bar{x}}$ = 85.6
$\sigma_{\bar{x}}$ $\approx$ 3.465
Work Step by Step
i) When we apply the central limit theorem, mean of the sampling distribution is given by $\mu_{\bar{x}}$ = $\mu$.
Therefore, $\mu_{\bar{x}}$ = 85.6
ii) Standard Deviation of the sampling distribution is given by, $\frac{\sigma}{\sqrt n}$.
$\sigma_{\bar{x}}$ = $\frac{20.5}{\sqrt 35}$ $\approx$ 3.465
