Question 3

Correct Answer:

Answered by Examlex AI Copilot

The two requirements for a probability sampling plan are:
1. Every element in the population has a known and non-zero chance of being selected for the sample. This means that every individual or item in the population must have an equal opportunity to be chosen for the sample, and the probability of selection must be quantifiable.
2. The selection of each element for the sample must be independent of the selection of other elements. This means that the selection of one individual or item for the sample should not influence the selection of another, and each selection should be made without bias or influence from previous selections. This ensures that the sample is truly representative of the population and that the results can be generalized with confidence.
