A researcher believes that students do better on a reading test when hearing a constant background sound. She divides a group of students into three random groups, has them read a passage (with different background sounds), and then gives them a test. The following are her results: Constant Sound 3 7 10 9. 4 8. Random Sound 6. 3 8. 7 2 4 1 No Sound 2 4 8 3 4 2 Can she say that there is a significant difference between any of the types of sounds?
