Solution :

Given that ,

2 = 16

standard deviation = = 4

n = 81

sampling distribution of standard deviation

=  / n = 4 / 81

= 0.44

The Central Limit Theorem allows us to make predictions about where a sample mean will fall in a distribution of sample means. One way it does this is by explaining (using a formula) how the shape of the distribution will change depending on the sample size.
