What is the standard error of the sampling distribution equal to when you do not know the population standard deviation?
You calculate the standard error using the data.
What is sampling distribution of the mean?
Thanks to the Central Limit Theorem, the sampling distribution of the mean is Gaussian (normal) whose mean is the population mean and whose standard deviation is the sample standard error.
Is the standard deviation of the sampling distribution of the sample mean is o?
NO
As the sample size increases the standard deviation of the sampling distribution increases?
