WebJul 13, 2024 · The number you see is the critical value (or the t -value) for your confidence interval. For example, if you want a t -value for a 90% confidence interval when you have 9 degrees of freedom, go to the bottom of the table, find the column for 90%, and intersect it with the row for df = 9. This gives you a t- value of 1.833 (rounded).
