Chances of getting into CMU H&SS compared to other cmu's other schools?

<p>I've heard that Mellon College of Science is one of cmu's top schools. So.. is the school of humanities and social sciences one of the difficult schools to get into compared to school of science? Also, how is it compared to the school of arts?
Just fyi, I'm planning on majoring econ&stats at H&SS if I'm accepted.</p>
