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: America was neutral at the beginning of the war.
Explanation:
Woodward Wilson proposed the entry of America into the war on April 2, 1917. Four days later, Congress approved it. Until that moment, America was neutral. In America, there was a general lack of public interest in entering the war. Also, the United States had economic reasons for withdrawing from the war. Namely, in the first years of the war, Britain, and France quadrupled the import of weapons from the United States, which brought the country a huge financial gain. The public supported the government's decision on neutrality, during which time there were active slogans addressed to then-President Wilson that read "He who saved us from the war."
As the war progressed, the U.S. government worried that they might run out of money from selling weapons to France and Britain if they lost the war. One of the key factors involved in the war was the sinking of American ships by Germany. Also, Germany offered Mexico a secret war alliance and the return of territories that Mexico had lost to America. These were the key factors that changed the American attitude towards neutrality.
Governments are more justified to censoring war news because:
· The Government know that everyone has a self-inflicted opinion on to which every right they have. So if they were to show such war news, citizens of different opinion on the matter at hand would argue and bicker over what is right in their own state of mind and in turn this situation could bring up riots and up risings and possible soil attacks made by the countries own people.
I hope this was able to help you, have a nice day. :)
