We're not going to assume it's a normal distribution, because this is a bad estimate. We're going to assume that it's something called a t distribution. And the t distribution is essentially, the best way to think about it is it's almost engineered. It's almost engineered, so it gives a better estimate of your confidence intervals and all of that when you do have a small sample size. And it looks very similar to a normal distribution. It has some mean. So this is your mean of your sampling distribution still.
