Mоff Gideоn believes thаt lаck оf sleep will decreаse grades. To test this, he recruits two of his friends who are Resident Assistants (RA) in two different dorms on his campus. He asks one RA to wake the people on their floor up twice a night for the last two months of the semester. In contrast, the other RA is to try to keep their floor as quiet as possible between the hours of 9 PM to 7 AM for the last two months of classes. Moff Gideon is concerned that if people know they are in an experiment, they might try harder in class, so he does not tell the students he is conducting the study. A- Identify AND describe the 3 principles of the Belmont Report and explain how Moff Gideon's research violates each principle (6 points)
