All of the students in their final year of law school at the University of Memphis were sent an email asking them to participate in a research study. Forty law students volunteered for the study and provided informed consent. All of the participants observed a videotape of a crime. Next, a fair coin was flipped to decide if each participantwould go to a room on the right or a room on the left. The twenty students in the room on the right attempted to choose the criminal seen in the movie from a lineup consisting of five people. The twenty students in the room on the left chose from a lineup consisting of ten people. Each of the subjects then judged their confidence in the person they selected as the criminal from 50% (no idea) to 100% (completely sure). 4. What is the researcher’s hypothesis (Use your best guess if it is not obvious)? 5. How many participants were in the study sample?
