Solve[Probability[x <= t, x \[Distributed] StudentTDistribution[2.964, 2.071, 5]] == 0.95 ,t]

If I do this with a NormalDistribution it works. Why doesn’t it work with StudentTDistribution?
How can I solve this problem?

Works fine for me in version 9. You may also try

Quantile[StudentTDistribution[2.964, 2.071, 5], 0.95]
