Question

Quizplus · Accepted Answer

The students at the university who will be used as subjects represent the study population, which is part of the theoretical population of all women who may be impacted by stress on their sleep cycles. Therefore, choice B is the best option as it accurately identifies the relationship between the subjects and the populations of interest. A representative sample (choice A) would need to be randomly selected from the study population, and a random sample (choice C) would not necessarily be representative of the theoretical population. Choice D is incorrect as the theoretical population is broader than the study population, which is only a subset of the theoretical population.
