You can put this solution on YOUR website! How do yo find the mean and standard error of the sample mean that is normally distributed with a mean of 10 and a standard deviation of 2 when the sample size is 25?
-----
The Central Limit Theorem says::
The mean of the sample means = The population mean
The std of the sample means = (the std of the population)/sqrt(sample size)
--------
Your Problem
mean of sample means = 10
std of sample means = 2/sqrt(25) = 2/5
