Question 630065: Consider a t distribution with 22 degrees of freedom. Compute P(t>= 1.44). Round your answer to at least three decimal places.
Consider a t distribution with 25 degrees of freedom. Find the value of C such that P(-c
Please help! I am soooo lost!

You can put this solution on YOUR website! Consider a t distribution with 22 degrees of freedom. Compute P(t>= 1.44). Round your answer to at least three decimal places.
----
P(t >= 1.44 when df = 22) = tcdf(1.44,100,22) = 0.0820
=============================
Consider a t distribution with 25 degrees of freedom. Find the value of C such that P(-c
-----
Center 0.99 on a t-distribution curve.
That leasves 0.005 in each tail.
Find invT(0.005,25) = -2.7874
-----
C = 2.7874
