SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Define systemmatic sampling
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size
STEP 2: Determine the answer
The option that follows the systematic sample of workers is the last option because it follows a fixed, periodic interval of "every 4th worker until 80 workers are selected".
Hence, the answer is:
The consultant takes a list of the workers and selects every 4th worker until 80 workers are selected.
