There is a 99.2% chance. If you multiply this times 2, you get 0.99. You get 0.9902. Let's say roughly 99% chance that any sample that a random sample mean is within 2.58 standard deviations of the sampling mean of our population mean, of the mean of the sampling distribution of the sampling mean, which is the same thing as our actual population mean, which is the same thing as our population proportion, so of p. We know what this value is right here. At least we have a decent estimate for this value. We don't know exactly what this is, but our best estimate for this value is this over here. We could rewrite this, and we could say that we are confident because we are really using an estimator to get this value over here.
