I am asked to do a single and multiple regression on various variables affecting wages using STATA and a data set. Afterwards I'm asked to:

record the coefficient estimates and the p-value for the 2-sided test.

The coefficient estimates are easy because stata gives them to you, but the p-test part...I have no idea how to do this.

I do know what a p-test is, I just don't know how I would set it up. From searching online I found that the hypothesis is (maybe) that a regression coefficient is zero?

Assuming that is what the test is for how do I set up the equation?

(0 - regression coefficient)/(sd/sqrt(n))

If I set it up as above, which sd do I use? would it be the sd of the dependent variable?

thanks for any help!
