So we got a total of, I already forgot, 642, 591. So it is 642 plus 591. If you viewed it as just one huge sample of 2,000 people, we got, get the calculator out, we got 642 plus 591 is equal to 1,233 divided by 2,000. Gives us 0.6165. And this is our best estimate of this consistent population proportion that is true of both men and women. Because we are assuming that they are no different. So we can substitute this value in for p to estimate the standard deviation of the sampling distribution of this statistic right over here.
