Answer:

3. t-test for the difference between means for two related samples.      

Step-by-step explanation:

It is given that a professor of UCI wishes to study what really the students remember from their elementary school days and other such stuffs that were very popular at that time.

therefore the professor put forward two test. In one of the test, he put some question from the elementary school and in other he put one question about a pop culture from that time. He used the same sample for both the tests.

So, since the professor involved the same set of students in his experiment for both the tests, so both the samples are related samples.

Therefore, the test uses is a t - test that is used for the difference between the related samples.
