An educator wishes to study the effects of sleep deprivation on the ability to concentrate. He decides to study the students in a calculus class.

The educator does not know which group a student belongs to when she or he comes to class. The study subjects are:
A)the groups assigned to sleeping either 6 or 8 hours.
B)the students participating in the experiment.
C)the students who do not fall asleep in class.
D)the students who are enrolled in any of the calculus classes.

The study subjects are the students participating in the experiment, as they are the ones the educator is studying in order to observe the effects of sleep deprivation on concentration. The other options (A, C, and D) are not the study subjects because they are either the groups assigned to a certain sleep schedule, students who do not fall asleep in class (which is not necessarily related to the study), or all students enrolled in calculus classes (which is not specific to the study).
