And if I want to figure out my sample standard deviation, I just take the square root of that. My sample standard deviation is just going to be the square root of my sample variance. So I take the square root of that value that I just had, which is 0.497. So actually, let me just round that up as 0.50. So my sample standard deviation is 0.50. Now, if you just look at this, you say, OK, well your best estimate of the percentage of people voting for A or B is really what you just saw here. Your best estimate of the mean is that 43% of people are going to vote for B and everyone else is going to vote for A.
