Question

Determine $\mu_{\bar{x}}$ and $\sigma_{\bar{x}}$ from the given parameters of the population and the sample size. Round the answer to the nearest thousandth where appropriate. $\mu = 25$, $\sigma = 12$, $n = 16$ $\circ \mu_{\bar{x}} = 25$, $\sigma_{\bar{x}} = 12$ $\circ \mu_{\bar{x}} = 6.25$, $\sigma_{\bar{x}} = 3$ $\circ \mu_{\bar{x}} = 25$, $\sigma_{\bar{x}} = 3$ $\circ \mu_{\bar{x}} = 25$, $\sigma_{\bar{x}} = 0.75$

          Determine $\mu_{\bar{x}}$ and $\sigma_{\bar{x}}$ from the given parameters of the population and the sample size. Round the answer to the nearest thousandth where appropriate.
$\mu = 25$, $\sigma = 12$, $n = 16$
$\circ \mu_{\bar{x}} = 25$, $\sigma_{\bar{x}} = 12$
$\circ \mu_{\bar{x}} = 6.25$, $\sigma_{\bar{x}} = 3$
$\circ \mu_{\bar{x}} = 25$, $\sigma_{\bar{x}} = 3$
$\circ \mu_{\bar{x}} = 25$, $\sigma_{\bar{x}} = 0.75$

Determine μx̅ and σx̅ from the given parameters of the population and the sample size. Round the answer to the nearest thousandth where appropriate.
μ = 25, σ = 12, n = 16
∘μx̅ = 25, σx̅ = 12
∘μx̅ = 6.25, σx̅ = 3
∘μx̅ = 25, σx̅ = 3
∘μx̅ = 25, σx̅ = 0.75
