So each ball we take, it is an independent pick. And we're gonna use those samples of two balls at a time in order to estimate the population mean. So for example, this could be our first sample of size two. And let's say in that first sample, I pick a one and let's say I pick a two. Well, then I can calculate the sample statistic here. In this case, it would be the sample mean, which is used to estimate the population mean. And in this, for this sample of two, it's going to be 1.5.
