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:
Retrograde amnesia
Explanation:
In psychology, when you suffer an injury, loss of consciousness or start having a disease (like dementia) you can get retrograde amnesia, which is the phenomenon by which you forget the events that took place just before the injury.
As opposed to the anterograde amnesia in which you forget the events that take place after the injury and therefore they cannot be stored into the long-term memory.
In this example, we are asked for the phenomenon that occurs when an individual experiences a loss of memory for experiences that occurred shortly before a loss of consciousness. Thus, this would be retrograde amnesia.
