Determine $$ \mu_{\mathrm{x}}^{-} $$and $$ \sigma_{\mathrm{x}}^{-} $$from the given parameters of the population and sample size.

Question

Hall Matthews · Accepted Answer

To find $$ \mu_{\mathrm{x}}^{-} $$ (estimated population mean) and $$ \sigma_{\mathrm{x}}^{-} $$ (estimated population standard deviation), use the sample mean and sample standard deviation. If estimating the standard error of the mean, divide the sample standard deviation by the square root of the sample size. Otherwise, use the sample standard deviation directly.

Determine \( \mu_{\mathrm{x}}^{-} \)and \( \sigma_{\mathrm{x}}^{-} \)from the given parameters of the population and sample size.
