In a study of simulated juror decision making, braden-maguire, sigal, and perrino (2005) investigated the type of verdict assigned given by study participants after they read a 12-page summation of a case involving a battered woman who had shot and killed her husband. of the 80 participants, 27 assigned gave the verdict of guilty, 49 gave the verdict of not guilty by reason of self-defense, and 4 gave the verdict of not guilty by reason of insanity. what type of chi-square statistical test should the researchers use to determine whether the distribution of verdicts differed from what could have been expected by chance?
