Answer to Question #44302 in Statistics and Probability for Joe

Question

Find the t value such that the area to the left of –t equals 0.1. Assume 25 degrees of freedom.

Answer 1

By tables, area to the left of (-1.316) for Student`s curve with 25 degrees of freedom is 0.1. So t=1.316. Besides, in correspondence of 25 degrees of freedom there is a 0.1 area at the right of t=1.316. Then there is a 0.1 area at the left of t=-1.316.
