The mean and standard deviation of the x sampling distribution for each of the following sample sizes will be
.
<h3>What is the distribution of the sample mean for large samples?</h3>
Suppose X has a distribution with mean
and standard deviation
then,
the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with a mean equal to the mean of X, and a standard deviation equal to 
Symbolically, we write it as:

A random sample is selected from a population with a mean = of 100 and a standard deviation = of 10.
The mean and standard deviation of the x sampling distribution for each of the following sample sizes.
If N=41

If N=130
