Final answer:
The standard error of the mean is based upon the standard deviation of the population. When performing a hypothesis test or constructing a confidence interval, the standard error of the mean is calculated as the population standard deviation divided by the square root of the sample size.
Step-by-step explanation:
The standard error of the mean is based upon the standard deviation of the population.
When performing a hypothesis test or constructing a confidence interval, the standard error of the mean is calculated as the population standard deviation divided by the square root of the sample size. This measure helps estimate the variability of the sample mean and is used to make inferences about the population mean.
