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.

A scientific theory is what you are talking about.
Answer:
The listener is overwhelmed with incoming information and has to decide which information will be processed and remembered.
Explanation:
Selective listening is the phenomenon of attention in which we processed information that we want to hear or we want to see. This called a type of mental filtering in which we tuned others thought and we filter that thinking when does not tune with us.
This is not called a bad habit or bad behavior. It is called the big problem For the speaker because you are unable to hear what some say you don't get the confrontation. The potential says that we often reject to hear what someone has says.
The answer is: because it is the means by which public will becomes public policy.
Members of the congress are elected by the citizens in order to carried out their aspiration to the lawmaking process.
The citizens cannot force their will to the government and directly vote for the law that must be passed by the government. BUT , they can elect a congress who has similar goals, value, principles as them and trust that congress to make the best possible decision for them.
Because of this, we can say that the lawmaking function of congress is an important means to make public will to become public policy.
