Question

Quizplus · Accepted Answer

The study aimed to determine the effects of stress on the immune system, and the comparison was done between college students undergoing a stressful series of exams and a group of students who were relaxing. Therefore, it can be inferred that the exam group would test lower for immune system chemicals since the stress of exams could have a negative impact on the immune system. Option A is incorrect because if the exam group tested higher, it would imply that stress had a positive effect on the immune system, which is not what the study aimed to find. Option C is incorrect because the relaxed group would not be expected to have lower immune system chemicals, as they were not undergoing the same stressors as the exam group. Option D is also incorrect because the study was designed to compare the effects of stress on the immune system between two groups, so the relaxed group's stability is irrelevant to the results.
