Milgram found that 65% of the real participants obeyed through the end of the study, giving what they thought was 350 volts to the confederate, which was considered "lethal". Given the infamous study and the negative attention it received, current researchers doubt that current (and more knowledgeable) participants would obey as much as the nave participants that Milgram used in the original study. Which is the research hypothesis?

H_a: Obedience = 65% or H_a: Obedience < 65%
