   Question

   Below is a regression equation of a moderation model. The dependent variable “PINC” is personal monthly income (net, in euros). “MAN” is a dummy variable (female = 0; male =1); “FULLTIME” is a dummy variable indicating whether a person works 32 hours or more (score 1) or less than 32 hours of paid work per week (score 0).

   PINC = 1381 + 644*MAN + 742*FULLTIME - 128*FULLTIME.

   Suppose we want to test whether the moderation effect (idem: interaction effect) of MAN on the relationship between FULLTIME and PINC is significant. What should we do then?

   
   
   1. TRUE: We should then check whether the value -128 is significantly different from 0.
   2. FALSE: We must then check whether the value 742 is significantly different from 0.
   3. FALSE: We must then check whether the difference between the value 742 and the value 644 deviates significantly from 0.
   4. FALSE: We must then verify that the difference between the value 742 and the value -128 is significantly different from 0.
   5. FALSE: We must then verify that the difference between the value 644 and the value -128 is significantly different from 0.
