And so, we could say the probability that p is within two times 0.05 is going to be equal to, 2.0 is going to be 0.10, of our mean is equal to 95. And actually, let me be a little careful here. I can't say the equal now, because over here, if we knew this, if we knew this parameter of the sampling distribution of the sample mean, we could say that it is 95.4%. We don't know it. We are just trying to find our best estimator for it. So actually, what I'm going to do here is actually just say is roughly, and just to show that we don't even have that level of accuracy, I'm going to say roughly 95%. We're reasonably confident that it's about 95% because we're using this estimator that came out of our sample.
