Question 1180689: Roll a fair die five times. List the results and take all random samples of size n = 3.
Calculate the population mean, population variance, and population standard
deviation. Illustrate the sampling distributions of the sample means and sample
variances and standard deviations.
I can't understand this. Please help me with this

We have the population 1,2,3,4,5,6

Population mean mu=%281%2B2%2B3%2B4%2B5%2B6%29%2F6=21%2F6=3.5
Population variance

%286.25%2B2.25%2B0.25%2B0.25%2B2.25%2B6.25%29%2F6
=2.91

Standard deviation delta=sqrt%282.91%29=1.70

Now, size of 3 is taken from the sample => 5C3=10+

In her post, @MathLover1 wrote many formulas and performed different calculations,

but, UNFORTUNATELY, they all are IRRELEVANT to the posed problem

and do not answer the posed questions.
