T-Distribution, Hypothesis Test... Using P-Vale Approach
This problem is confusing me quite a bit. I know how to do the classical method, no problem. But the P-Value approach is throwing me for a loop. I know how to get via the calculator but manually it's a little tricky. For example, this becomes t(t-2.488)=.0086... I have done the DF, have looked on the right of the T-Table and it's still giving me nothing. Can somebody tell me how that .0086 was obtained? Thanks!

What resolution does your t-table go to? If it has 2.49 and 2.48 you should use linear interpolation to get the result.
All you have do is find P(T < -2.488) using your t-tables and get the value of that probability.
