Thank you for your question - this one is a little less obvious than some of the other conclusions (which may lead with transitions such as "thus", "therefore", or "so". One other key to determining which statement is a conclusion is that conclusions need to be based on evidence. In this paragraph, the author uses the evidence that "the record shows that in 60% of such cases, the judge has decided in favor of women" to arrive at the conclusion that "the record demonstrates that the judge has not discriminated against women in cases...".
Because the last sentence references and depends upon the second sentence as evidence, we can consider it to be the conclusion. Conclusions, when not denoted by transition words, or a "call for action", can also be found in that they are the dependent "effect" of a cause-and-effect relationship.
To summarize, the telltale signs of a conclusion in a Critical Reasoning passage are:
1) Concluding transitional language ("therefore", "so", etc.)
2) A call for action ("we should", "they must", etc.)
3) The effect of a cause-and-effect relationship ("because of X, Y must be the conclusion")
