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.

According to the central principle of utility, actions are right in proportion, as they tend to promote happiness, and wrong, as they tend to produce the reverse of happiness (pain).
<h3>
What is the principle of utility?</h3>
The concept of the principle of utility refers to the standard that determines whether or not any action is acceptable. According to the propensity it shows to either increase or decrease the happiness of the party whose interest is under consideration, or, to put it another way, to support or oppose that happiness.
For instance, the utilitarian viewpoint holds that you should select the flavour of ice cream that will make you feel the happiest if you are making a decision for yourself. If you like chocolate but detest vanilla, go with chocolate for the delight it will provide, and stay away from vanilla because it will make you unhappy.

Answer: d) Discriminative Stimulus
Explanation:
Discriminative stimulus is defined as term in classical conditioning in which the stimulus is utilized for obtaining a particular feedback from someone.It helps in getting the responses that are desired by an individual and increase those response accordingly.
According to the situation it also describes discriminative stimulus as Tommy prefers to ask about staying up past the bedtime from babysitter as he gets the desired response in the form of permission to stay up. His parent did not let him stay up late so the feedback was not favorable to Tommy's desire.
Other options are incorrect because stimulus class have same element consisting cluster of stimulus. S-delta is the stimulus in which non-enforced behavior is present. Reinforcer is stimulus that encourage for gaining particular response.
Thus, the correct option is option(d).
