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: False
Explanation:
High-valence in terms of psychology is defined as the natural attractiveness which is related to emotion of the person.It creates the feeling of positive valence where goodness concerned with any place, situation or event is induced.Information's impact in terms of feeling highly arousal after hearing it such as excited .
According to the question ,John does not see the reward as high valance.he does not like travelling and trip to the places that does not speak the same language.So ,this information does not give him excitement arousal .So, it is a low valence reward for him.
Thus, the statement in question is false.
