The following scatter plot shows the test scores of a group of students who watched movies for different amounts of time in a week: A graph shows Hours Watching Movies on x axis and Test Score on y axis. The graph is shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 100 at increments of 10. The ordered pairs 0, 99 and 0.2, 98 and 1.2,82 and 1.4,86 and 2.3, 81 and 2.5,90 and 2.8,97 and 3.2, 88 and 3.5, 85 and 4.2, 61 and 5.3, 73 and 5.6,69 and 6.7,66 and 6.9,55 and 7.2,68 and 7.7,43 and 8,36 and 8.2,41 and 9,30 are shown on the graph.
What will most likely happen to students' test scores if the number of hours they watch movies increases? (1 point)

Test score will increase, because the graph shows a positive association
Test score will increase, because the graph shows a negative association
Test score will decrease, because the graph shows a negative association
Test score will decrease, because the graph shows a positive association
