1. A psychologist wants to test if background music affects concentration during tests. 60 students are divided into two groups; one group (n=30) takes a math test with classical music playing in the background, while the other group (n=30) takes the same test in silence. The test scores are recorded, with higher scores indicating better performance. The psychologist wants to know if background music improves test scores. The dataset can be found in the picture below. Using the 4-step hypothesis testing, what should this psychologist conclude? Make sure to show work and go through all 4 steps. After you make your conclusion, put your results either in APA or in a clear way.

Data: Background music
