So that's mu right over there. And what would be the assumption that that would be, the no news here? Well, it would be 500 milliliters. That's the target value. So it's reasonable to say, well, you know, the null is it's doing what it's supposed to, that where the actual mean for the batch is actually what the target needs to be, is actually 500 milliliters. Some of you might have said, hey, wait, didn't they say the amounts in the sample had a mean of 503 milliliters? Why isn't this 503?
