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. reverential isn't branch of government
I don't know limited and unlimited countries, but this is something that you often say of government: a limited government must obey some kind of rule, while an unlimited government is an absolute government and is free to do everything (including kill its subjects)

Answer:
A) Alter its own spending, taxes, and/or the amount of money in circulation.
Explanation:
In situations of economic warming and inflation the government can act to influence citizens' spending to cool down economic activity to lower inflation. Inflation is a monetary phenomenon caused by excess currency in the economy. Thus, the government can reduce its spending, because it is an important player, which makes government consumption has a significant weight in economic warming. In addition, the government can take steps to curb citizen consumption through restrictive policies such as raising taxes. Finally, the government may sell government bonds to wipe out the monetary base. When the government sells bonds, people stop consuming at present to earn future income from public bonds. Thus, the government causes the money in circulation to decrease.
