If you have samples of n 1 equals 22 and n 2 equals 20, in performing the pooled-variance t test, you have 40 degrees of freedom.

The t-test method is a method where we analyze two sets of data which both these data are independent of each other. This pooled variance test helps us in getting the overall variance in both these different sample sets when we know that both the sample sets are almost equal.

To calculate degrees of freedom, we have the formula

df = n1 +n2 -2

According to the question, n1= 22 and n2= 20

Therefore, degree of freedom= 22 +20 -2 = 40

Hence, degree of freedom is 40.
