But you can still derive useful information about the sampling distribution without knowing the population. And theoretically the standard deviation of the sampling distribution should be equal to sn which would be 9 20 2012. This is the currently selected item.
When using the sample mean to estimate the population mean some possible error will be involved since the sample mean is random.
