You know, I was thinking the same thing. 12.90% just has a nice ring to it, doesn't it? Although, I shouldn't be choosing answers based on how they sound!
Hmm, I'm leaning towards option B, 12.90%. The distribution looks somewhat symmetrical, and that feels like a reasonable standard deviation for stock returns.
Oh man, this is going to test our understanding of statistics. I think the key here is to really focus on calculating the standard deviation from the given probability distribution.
