How do r correlation coefficient and p value connect with N (number of subjects)

[CARMENNN]

I know that: r(291)=.25 and p=.01. Which is N?

a. N=291
b. N=289
c. N=292
d. N=293

Thank you.

Hint: what are the degrees of freedom? How are the degrees of freedom computed?

 

[CARMENNN]

Then the right answer is c.292, because df=N-1.

Df is N - 2

Sorry.
