1. Select n520 experimental units from a population of size N 5500. (hint: Since you need to use threedigit numbers, you can assign 2 three-digit numbers to each of the experimental units. For example, unit 1 would correspond to random numbers 001 and 501, unit 2 would correspond to 002 and 502, and so on.) use the random number table to identify the experimental units to be included in a simple random sample
