Help with Statistics

Hello, my name is Tyler. I'm new to this and I have never had to ask for help on a statistics problem before.



With Ha : ?>181
you obtain a test statistic of t=2.597 with degrees of freedom = 12 .
Find the p-value accurate to 4 decimal places.

I do not know where to begin, let alone know how to do this problem.
Could you help me please?

At what level of significance would 2.597 be a boundary value?
