Question 1118539: A population consists of the following five values: 2, 2, 5, 6, and 8.

List all samples of size 3, and compute the mean of each sample. (Round your mean value to 2 decimal places.)
Compute the mean of the distribution of sample means and the population mean. Compare the two values. (Round your answers to 1 decimal place.)

5C3 = 5! / (3! * (5-3)!) = 10 samples of size 3
:
population is 2, 2, 5, 6, 8 mean is 4.6
:
2, 2, 5 mean is 3
:
2, 2, 6 mean is 3.33
:
2, 2, 8 mean is 4
:
2, 5, 6 mean is 4.33
:
2, 5, 8 mean is 5
:
5, 6, 8 mean is 6.33
:
2, 5, 6 mean is 4.33
:
2, 5, 8 mean is 5
:
2, 6, 8 mean is 5.33
:
2, 6, 8 mean is 5.33
:
*************************************************************************
population mean is 4.6
:
mean of the distribution of sample means is (3 +3.33 +4 +4.33 +5 +6.33 +4.33 +5 +5.33 +5.33) / 10 = 4.598 is approximately 4.6
:
population mean is equal to the mean of the distribution of sample means
