The estimated standard error of the mean is equal to the standard deviation of the sample, divided by the square-root of the size of the sample, less one. This formula represents the standard deviation of the sampling distribution of the mean and is used to estimate the precision of the sample mean as an estimate of the population mean. The other options do not correctly represent the formula for the estimated standard error of the mean.
