The best choice would be an independent t-test, which is used to compare the means of two independent groups. This test is appropriate for this situation since Dr. Smith has two distinct groups (one that listens to headphones frequently and one that does not) and wants to see if there is a significant difference in their ability to perceive high-pitched sounds.
