For the critical value Tav what is the area under the curve

For the critical value T(a,v), what is the area under the curve to the right of t(a,v) in the t-distribution with v degrees of freedom?

Solution

In t-table goes to row for degree of freedom v and search for your critical value. Find the given critical value. After that see the one tailed probability. This is the area to right of the critical value. For example if v=9 , and critical value is 1.833 so area right to critical value is 0.05.
