Here n=5 and 7V=150. Assign serial numbers 001, 002,….,150 to the 150 units in the population. Since 150 is a three-digit number, we merely read three-digit random numbers presented in the Appendix. WebbFor example, to select a sample of 100 from a population of 400, you would need a sampling interval of 400/100 = 4. Therefore, K = 4. You will need to select one unit out of every four units to end up with a total of 100 units in your sample. Select a number between one and K at random. flower field in long island
