2. What is the population mean of 4, 6, and 5?
3. If the population standard deviation of data set is 6.0, what is the population variance?
4. Consider the population consisting of the values 4, 6, 8. What is the mean of the sampling distribution of means?
5. A population consists of values 1,4,7. Consider all possible samples of size 2 that can be drawn without replacement from this population. What is the variance of the sampling distribution of means?
