a.
what is the population mean?
We have population values ,,,, population size

b.
what is the population variance?

c.
what is the population standard deviation?
≈

d. We have population values ,,,, population size and sample size .
Thus, the number of possible samples which can be drawn without replacement is

what is the mean of the sampling distribution of means?

The mean of the sampling distribution of the sample means is equal to the the mean of the population.
