So what was the sample mean that we actually got? It was 0.43. So if we're within 0.1 of 0.43, that means we are within 0.43 plus or minus 0.1 is also, roughly, we're reasonably confident, it's about 95%. And I want to be very clear. Everything that I started, all the way from pure and brown to yellow to all this magenta, I'm just restating the same thing inside of this. It became a little bit more loosey-goosey once I went from the exact standard deviation of the sampling distribution to an estimator for it. And that's why this is just becoming, I kind of put the squiggly equal signs there to say, we're reasonably confident.
