WebLecture III: Confidence Intervals and Contingency Tables Reporting the confidence interval of the mean of a univariate distribution is an intuitive way of conveying how sure you are about the mean. CI s are especially useful when reporting derived quantities, such as the difference between two means. 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.
