   Question

   An experimental research study evaluating the association between $Y$ = performance, $S$ = dummy variable Sex ($girl=1$) and $G$ = dummy variable Reward ($reward =1$) results in the following regression equation: $Y’ = 20+6S–4G$.

   Hanneke is assigned the reward condition and has a performance of 23. What is her predicted performance and what is her residual $Y_{i}-{Y}'_{i}$?

   
   
   1. FALSE: predicted performance: 22 ; residual: -1
   2. FALSE: predicted performance: 23 ; residual: -2
   3. TRUE: predicted performance: 22 ; residual: +1
   4. FALSE: predicted performance: 23 ; residual: +2
