List all 4 possible SRSs of size n = 3, calculate the minimum age for each sample, and display the sampling distribution of the sample minimum on a dotplot with the same scale as the dotplot in Exercise 20. How does the variability of this sampling distribution compare with the variability of the sampling distribution from Exercise 20? What does this indicate about increasing the sample size?

The small population of 4 cars listed in the table.

Color .................... Age (years)
Red ..................................... 1
White ................................. 5
Silver .................................. 8
Red ................................... 20

Exercise 20.

List all 6 possible SRSs of size n = 2, calculate the minimum age for each sample, and display the sampling distribution of the sample minimum on a dotplot. Is the sample minimum an unbiased estimator of the population minimum? Explain your answer.
