Consider a population consisting of 3, 6, 7, 9, 10, 4, and 8. Suppose samples of size 2 are drawn from this population. Describe the sampling distribution of sample means. What is the population mean?
The population mean is: . All samples of size and their means are given in the table:
There are different samples of size 2.
The sampling distribution of sample means is given in the following table:
Thus, the sampling distribution of sampling means is given in the table above. The population mean is approximately equal to .
