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.

Answer:
To achieve his purpose, Jackson encouraged Congress to adopt the Removal Act of 1830. The Act established a process whereby the President could grant land west of the Mississippi River to Indian tribes that agreed to give up their homelands.

The Puritans wanted to reform the existing religion because they believed that The English Reformation had a lot of Catholic influence. Besides, both fled England to escape from persecution under the King's rule so the Puritans settled in Massachusetts and the Separatists settled in Plymouth Rock.
