Consider a finite population with five elements labeled A, B, C,
D, and E. Ten possible simple random samples of size 2 can be
selected.
(a)
List the 10 samples beginning with AB, AC, and so on. (Enter
your answers as a comma-separated list.)
(b)
Using simple random sampling, what is the probability that each
sample of size 2 is selected? (Enter your probability as a
fraction.)
(c)
Assume random number 1 corresponds to A, random number 2
corresponds to B, and so on. List the simple random sample of size
2 that will be selected by using the random digits 9,
0, 2, 6, 2, 3, 1.
