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.

Genocide Watch in the U.S. and the Green Belt Movement in Kenya are examples of <u>"Nongovernmental Organizations".</u>
The Green Belt Movement (GBM) was established by Professor Wangari Maathai in 1977 under the sponsorship of the National Council of Women of Kenya (NCWK) to react to the necessities of provincial Kenyan ladies who announced that their streams were becoming scarce, their nourishment supply was less secure, and they needed to walk further and further to get kindling for fuel and fencing.
