Sociology 63993—Exam 3—Page 1 S o c i o l o g y 6399 3 E x a m 3 M a y 1 0 & 1 2, 2011 I. True-False. (20 points) Indicate whether the following statements are true or false. If false, briefly explain why. 1. If a model fails the Brant test, Manova should be used instead. 2. The probability of an event occurring is .5.
