WebSo we want to find a 95% confidence interval. And as you could imagine, because we only have 10 samples right here, we're going to want to use a T-distribution. And right down here I have a T-table. And we want a 95% confidence interval. So we want to think about the range of T-values that 95-- or the range that 95% of T-values will fall under. To calculate a confidence interval around the mean of data that is not normally distributed, you have two choices: 1. You can find a distribution that matches the shape of your data and use that distribution to calculate the confidence interval. 2.
