And your sample size is small. And you're going to use this to estimate the standard deviation of your sampling distribution. You don't assume your sampling distribution is a normal distribution. You assume it has fatter tails. And it has fatter tails, because you're essentially underestimating the standard deviation over here. Anyway, with all of that said, let's just actually go through this problem. So we need to think about a 95% confidence interval around this mean right over here.
