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:
7.77
Explanation:
d= m/v
18.5 / 2.35 = 7.87234x2.35= 18.5. so the answer is 7.77
Answer:
c. They are the same
Explanation:
I would say they are the same. It may be more difficult because if you start a protest, people might not support you because they don't want to get in trouble. If it was easier, you might have those types of schools where you start a protest and the big and bold people don't care what happens to them, which would help you with the protest. It actually all depends on who would actually want to help you whether they are your friends or not. It basically depends on what caused the protest.
Hope this helped!!!
