Answer all questions with explanation

1)If you have a maximized log-likelihood value of 124 with df = 3 for Model M and the saturated model has a maximized log-likelihood value of 128 with df = 7 what is the value of the Likelihood ratio test statistic?

2) If you have a maximized log likelihood value of 76 with df = 4 for the saturated model and model M has a maximized log likelihood value of 72 with df = 2 how many degrees of freedom should the Likelihood ratio test have?
