nlexa [21]

Answer:

C. The sample is carefully screened to ensure that it contains, proportionately, people with the same demographic profiles as encountered in the population.

Step-by-step explanation:

Sampling

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

When choosing a sample, you have to be careful, to avoid choosing a biased sample.

In this question:

Option A is not correct, as this wouldnt be representative of the entire population, since there is expected to be a significant number of people without these skills.

Option B is not correct, as we would not have a sample.

Option D is not correct, as a quickly selected sample could lead to bias.

Option E is not correct, as it could also lead to bias.

So the answer is given by option C.
