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.

The most common outcome of an off-year election is a win by the minority party going into the election.
Turnout is typically lower during off-year elections, and so the general consensus is that the minority party's die hard voters are the most motivated to vote out the people they oppose.
They are more free as they used to be affected by communism :)
