Consider the following five bundles of pens containing the quantities shown below.
Bundle Number of Pencils
(Population)
1 30
2 18
3 30
4 33
5 36
(a) How many different samples of two bundles each are there?
(b) List all possible samples of size two and compute the mean of each sample.
(c) Calculate the population mean and compare it to the mean of the sampling distribution.
