   Question

   Two linear mixed models are used: an “empty” model with no fixed effect of time (2 parameters, -2Log-Likelihood=2563.90), and a model with a linear fixed effect of time (3 parameters, -2Log-Likelihood=2561.57).

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

   
   
   1. FALSE: $\chi^{2}(df = 1) = 2.33;\;p < .05$
   2. TRUE: $\chi^{2}(df = 1) = 2.33;\;p > .05$
   3. FALSE: $\chi^{2}(df = 1) = 5.43;\;p < .05$
   4. FALSE: $\chi^{2}(df = 1) = 5.43;\;p > .05$
