Answer:
Last option is the correct answer.
Explanation:
A reference group could be defined as one that sets or establishes the standard to compare individuals or other groups -behavior and attitudes are important, but not the only things: incomes, expenses, among others could be required as part of the reference group, in example. This way, it is possible to judge others' behavior.
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:
TR = P * Q, or Total Revenue = Price * Quantity.
Explanation:
The main content of the passage is to present a possible situation in which a violent leader imposes the law on the country by force ("at the point of the sword"), which presumably leads to many deaths. This was what has happened, in Paine's interpretation under William the Conqueror in England. The intention is to show that this situation is undesired in America and to encourage Americans to fight against such a government.
