From the data, we can see that all points are spread out evenly.
So, we have cases with both less time watching and lower scores, less time watching and greater grades, and we have more time watching and lowers scores and more time watching and greater grades.
So, there is no tendency on the data, it is close to random.
So, there is no relationship, in this case, for time watching TV and scores.
So, the correct alternative is the fourth alternative.
