Kindly answer the following problem:

The sound waves produced by the music that we hear reach our brain by converting them into electrical signals which then travel to the eighth cranial nerve of our brain. Have you tried listening to music while studying? In the early 1990s, an experiment by Raucher and his colleagues revealed that listening to classical music could improve memory. So, does listening to music help or hinder students' learning? A college instructor wishes to test this so-called "Mozart Effect" on a random sample of 45 students. Each randomly selected student was assigned to study in a classroom under a certain environment (Classrooms X, Y, and Z). The students were then given a memorization task to be accomplished within 10 minutes. While performing the task, the students in Classroom X listened to classical music, students in Classroom Y listened to video game music, and students in Classroom Z sat in silence. At the end of the task, the students were given a 20-item test and their scores were recorded.
