The standard error of the mean is given by
A) $\frac { \sigma } { \sqrt { n } }$
B) $\mu - \bar { x }$
C) $| \mu - \bar { x } |$
D) $\mu \pm \sigma$ 2 Describe the distribution of the sample mean: nonnormal population.

Question

Quizplus · Accepted Answer

The standard error of the mean is calculated as the population standard deviation ($\sigma$) divided by the square root of the sample size ($n$), which is accurately represented by option A: $\frac { \sigma } { \sqrt { n } }$. This formula is used to estimate the variability of the sample mean around the population mean.
