And then you add all of that together, and you indeed do get, so that's 10. And so this is a 14. You do indeed get 2,401. So that's the minimum sample size that Della should take if she genuinely wanted her margin of error to be no more than 2%. Now, it might turn out that her margin of error, when she actually takes the sample of size 2,401, if her sample proportion is less than 0.5, or greater than 0.5, well, then she's going to be in a situation where her margin of error might be less than this, but she just wanted it to be no more than that. Another important thing to appreciate is, it just, the math all worked out very nicely just now, where I got our n to be actually a whole number, but if I got 2,401.5, then you would have to round up to the nearest whole number because you can't have a, your sample size is always going to be a whole number value. So I will leave you there.
