If your p-value (Prob > chi2) is less than your chosen level of
significance than you can conclude that you rejected your null
hypothesis. You did not say which level of significance you have
chosen, so I'll assume you use the customary but arbitrary 5% level.
0.0000 is less than .05, so you reject the null hypothesis. The null
hypothesis is that the cuts are equal. So you reject the hypothesis
that the cuts are equal.
