Quizplus · Accepted Answer

When researchers conduct a survey questioning all members of a population, it is called a census. On the other hand, when researchers question a subgroup of the population, they are employing a sample. Therefore, the correct option is D, census for questioning all members and sample for questioning a subgroup. Option A and B are incorrect as they both include confidence interval, which is not related to the type of survey being conducted. Option C is also incorrect as it suggests that sampling is being done for the entire population, which is not possible.
