Student's $t$ Distribution

For selected probabilities, a, the table shows the values $t_{v,a}$ such that $P(t_v > t_{v,a}) = a$ , where $t_v$ is a Student’s $t$ random variable with $v$ degrees of freedom. For example, the probability is .10 that a Student’s $t$ random variable with 10 degrees of freedom exceeds 1.372.
