Chi Squared Distribution Test in Excel

Question

I calculated a likelihood ratio on two likelihoods from my research (LhRatio = 2 * (Time Slice Lh – Normal Lh)). I'm testing a model which is a special case of my null meaning my likelihood ratio should be equal to a chi square statistic. I therefore tested my LR with the Chi Square Dist formula on excel (CHISQ.DIST(B7,2, TRUE)). What do my output values tell me? Some example values i've received are 0.3 and 0.9.
