99 confidence interval t score

• What is the t-value for a 90% confidence interval?

  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).

• What is the critical value for a 90% confidence interval?

  Find the critical values for a 90% Confidence Interval. NOTICE: A 90% Confidence Interval will have the same critical values (rejection regions) as a two-tailed z test with alpha = .10. The Critical Values for a 90% confidence or alpha = .10 are +/- 1.645.
