A psychologist noted that people have more difficulty sleeping in a bright room than in a dark room. She measured whether the intensity of the light could predict the time it took a sample of 4 participants to fall asleep. The data for this hypothetical study are listed in the following table.

Intensity of light (in watts): (X): 5, 10, 20, 40

Time it took to sleep (in minutes): (Y): 9, 18, 29, 35
