Consider a population consisting of the following five values, which represent the number of DVD rentals during the academic year for each of five housemates:

a. Compute the mean of this population.

b. Select a random sample of size 2 by writing the five numbers in this population on slips of paper, mixing them, and then selecting two. Compute the mean of your sample.

c. Repeatedly select samples of size 2, and compute the value for each sample until you have the x values for 25 samples.

d. Construct a density histogram using the 25 values. Are most of the values near the population mean? Do the values differ a lot from sample to sample, or do they tend to be similar?
