We have 642 1s, the rest are 0, so we have 642 in the numerator. We have 1,000 samples. 642 divided by 1,000 is 0.642. So you could view this as a sample mean or as a sample proportion. And if you do the same thing for the women, the sample proportion is going to be 0.591, or you could even just view this as the sample mean of the sample of 1,000 women. We're the ones voting for it, there's 1, the rest are 0. And just to visualize it properly, let me draw the sampling distribution for the sample proportion.
