And so these need to be truly random samples. So hopefully we met that condition. The second is that the expected value for any of these data points have to be at least equal to five. And so we have met that condition. These are all at least equal to five. And then the last condition is the independence condition that we are either sampling with replacement, or if we're not sampling with replacement, we have to feel good that our samples are no more than 10% of the population. So let's assume that that is the case as well.
