which type of association would you expect between number of hours studied for a test and the score on the test?

I would expect a positive association.

Step-by-step explanation:

There are three main types of associations: positive, negative, or no association.

A negative association is like hours exercised and weight. The more hours, the less you will weigh (hopefully). This is a positive association, because I expect that the more hours you study, the better you will do on the test! Of course, this is a generalization, but it makes the most sense.

It can be either strong or weak. This is pretty subjective, so it's up to you whether you think the association would be strong or weak, but I think it would probably be pretty strong.
