   Question

   Suppose you have three equally sized groups (variable medication level) with the following group averages on variable depression: Mean group medication low: M = 40 Average group medication medium: M = 30 Mean group medication high: M = 20

   To represent the effects of medication level on depression, you set up a regression equation with two dummy variables. You choose group medication high as the reference group. In the regression equation:

   I. the constant equals 20 II. the regression coefficient of the dummy for group medication low equals 20.

   
   
   1. TRUE: I is correct, II is correct
   2. FALSE: I is true, II is false
   3. FALSE: I is not correct, II is correct
   4. FALSE: I is not right, II is not right
