Question 1151236: Calculate the degrees of freedom associated with a small sample test of hypothesis test for (u1-u2) assuming o1^2≠o2^2 and n1=n2=20
u=mean
o^2= variance sd
I was not given the values for the variance. This is all I have to solve the problem.

You can put this solution on YOUR website! Since the sample sizes are equal, the degrees of freedom = 20 + 20 - 2 = 38
:
Note if the smple sizes are not =, the degrees of freedom = smallest sample size - 1
