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: My commitment is currently to do my best as a psychologist to contribute to the well-being of children in vulnerable conditions.
Explanation:
I work as a psychologist with children of initial and primary level in a low-income school. The school is located in an area where there are many deficiencies, which is defined as a school with vulnerability. One of my biggest commitments is to do a good job daily to help children with various difficulties.
The lack of basic elements is not only present but also that many of these children are in environments that interfere negatively with their education. Many receive both physical and verbal abuse, family dysfunction is present in their homes, the difficult way to get to school and often not having to eat also influences. Every day I try with a smile to lift the spirits of a child, I always listen to them and try to have the best attitude with them. I commit to being a positive figure in their lives, where they understand that there are people in the world who are willing to help and who can also trust.
My commitment also involves helping them and in turn, they help me because they teach me that from humility many things can be achieved. Every day I promise to improve in some areas where I am failing since these children need the best to overcome their adversities. Within my commitment is to be a model for them, where I take care of my expressions and my actions so that they are motivated to copy positive behaviors.
It is a difficult job but at the same time gratifying, there is no better gesture than listening thanks to someone who has helped you to overcome.

The correct answer to this open question is the following.
You forgot to attach the section "English mariners improve seamanship." However, we can comment on the following.
Jamestown colonists had to use every resource they had wisely because they faced many problems when they arrived at the North American territory in 1607.
At the beginning of the settling, the colonists had many problems to survive due to the lack of supplies, the weather, and the general conditions of the new land. They could overcome the situation with the help of the Native American Indians. However, years later the relationship got complicated and different issues started to create serious issues between Native Indians and white English settlers.
So that is why they had the develop maritime skills to take advantage of the rivers and the sea to succeed.
