1.What is the mean, variance and standard deviation of the population?

2.How many different samples of size n = 5 can be drawn from the population? List them with their corresponding mean.

3.Construct the sampling distribution of the sample mean.

4.What is the mean of the sampling distribution of the sample mean? Compare this to the mean of the population.

5.What is the variance of the sampling distribution of the sample mean?
