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. Suppose we use Excel's RAND function to assign random numbers to the five elements: A (.7266), B (.0476), C (.2459), D (.0957), E (.9408). List the simple random sample of size 2 that will be selected by using these random numbers.
