math 170A vs. Stats 100A

<p>so for my major, math/econ, i have to take either math 170a or stats 100a. It looks like stats 100a will fill up much quicker then math 170a this q. I've heard stats 100a is much easier, if any of you have heard anything, is there much truth in that or are they similar courses? also are they proof-based classes? any insight on either one of these two classes would be appreciated.</p>
