Figure:
A researcher examined whether interrogators who expect a suspect to be guilty,rather than innocent,use more persuasive interrogation techniques.The researcher created a laboratory situation in which students (the "suspects")were randomly assigned to actually commit a crime or not commit a crime by following a set of instructions given to them.Student interrogators then interviewed a suspect;they were randomly assigned to conditions that led them to believe the suspect was guilty or innocent of the crime.Observers rated the effort used by interrogators to obtain a confession using a 1-10 rating scale (higher scores indicate greater effort).
Suppose the researcher observed the following means for each group:
-The means used to describe the main effect of Suspect Status are
A)6.0 and 6.0.
B)-6.0 and 0.0.
C)12.0 and 6.0.
D)6.0 and 9.0.

The means for each group in the Suspect Status main effect are 6.0 and 9.0. This suggests that overall, the interrogators used more persuasive interrogation techniques when they believed the suspect was guilty (9.0) compared to when they believed the suspect was innocent (6.0). Option D is the only choice that correctly reflects these means.
