   Question

   In a regression analysis to predict dependent variable Y from predictor X, the linearity assumption is being checked. The following output is available:

   

   
   
   1. FALSE: F-change is significant, so the linearity assumption is satisfied.
   2. TRUE: F-change is significant, so the linearity assumption is not satisfied.
   3. FALSE: F-change is not significant, so the linearity assumption is satisfied.
   4. FALSE: F-change is not significant, so the linearity assumption is not satisfied.
   
   

   Solution

   F-change (comparing model 1 to model 2) is significant, indicating that adding x-squared is a significant improvement to the model and therefore the linearity assumption is not satisfied.
