   Question

   Two linear mixed models are used: an “empty” model with no fixed effect of time (2 parameters, -2Log-Likelihood=413.45), and a model with a linear fixed effect of time (3 parameters, -2Log-Likelihood=409.25).

   Perform a likelihood-ratio test to test whether there is a linear fixed effect of time.

   
   
   1. TRUE: $\chi^{2}(df = 1) = 4.20;\;p < .05$
   2. FALSE: $\chi^{2}(df = 1) = 4.20;\;p > .05$
   3. FALSE: $\chi^{2}(df = 3) = 4.20;\;p < .05$
   4. FALSE: $\chi^{2}(df = 3) = 4.20;\;p > .05$
