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.
b. using simple random sampling, what is the probability that each sample of size 2 is selected?
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 8 0 5 7 5 3 2.
