(3)

Decide a random starting point and a fixed periodic interval.The starting point is got by random number generator. The fixed periodic intrval is calculated by dividing the population size by the sample size = 20. From the pile of federal tax return, first select sample1 at the starting point. Sample 2 will be afther the fixed periodic interval. Thus, all the 20 samples are taken.
