Answer:
Work sample exercise
Explanation:
This is an example of a work sample exercise. A work sample exercise is an exercise in which a person is tested on everyday activities that are performed at the job in question. These tests are usually a good indicator of a person's ability to operate in the everyday life of a company. In this example, you are being tested in this way because you are faced with tasks such as memos, letters, emails and phone messages.
Answer:
There are 4 hemispheres, eastern, western, southern, and northern. The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres. It is also known as a half-sphere. And geographers, or people who study Earth, have divided the planet into two sets of two hemispheres. These are the Northern and Southern hemispheres and the Eastern and Western hemispheres.
Explanation:
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.
