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.

1)_ To begin with, Erik Erikson was a german-american psychoanalyst known for his theory on psychological development of human beings in which he developed a concept called ''the identity crisis'' and ''the stages of psychosocial development''. In addition to that last one, the stage number 5, the period of the adolescence, Erikson called it <u><em>''Fidelity, Identity vs Role Confusion'' </em></u>and it establishes that the main questions a person asks himself is that: who is he, how he fits in and what should he do for the rest of his life. In that stage the person seeks for his own unique identity.
2)_ To begin with, a CT Scan or Computed Tomography Scan is the name given to technique that uses X-rays to produce images of a specific area of a scanned object and that allows the user to see inside that object. Moreover, <u><em>CT scanning of the head is typically used to detect tumors</em></u>.
