Dr. Aukuculus is exploring the effects of bluelight on college students' sleep schedule. He uses 16 students to test his theory, 8 using bluelight 30 minutes before they go to bed and 8 using no bluelight 30 minutes before bed.

He has collected data to support his hypothesis, the higher the number the longer it takes the student to fall asleep, and the lower the number the shorter it takes the student to fall asleep. Values are the number of minutes.
