The Following Values Have Been Calculated Using the T DIST

Short Answer

The following values have been calculated using the T DIST and T INV functions in Excel^®. These values come from a t- distribution with 15 degrees of freedom.
These values represent the probability to the right of the given positive values. These values represent the positive t- value for a given probability in both tails (sum of both tails).
-What would be the t-values where 0.10 of the values are in both tails (sum of both tails)?
