Explanation / Answer

We need to take random numbers between 0001 and 5000 and reject others.

Let's start from row 28 and column 15

3413, 4783, 1755, 1425, 4770, 4570, 3426, 1075, 3078, and 3159.

b) Random start = 045 = 45

Then we need to add (5000/10) = 500 in 45 to obtain the next systematyc sample

So second systematic sample = 500 + 45 = 545

Third systematic sample = 500 + 545 = 1045

So we get 45, 545, 1045, 1545, 2045, 2545, 3045, 3545, 4045, and 4545.

c) Yes the selected random sample in part a) and part b) are different because we used different selection procedure.
