A psychologist was trying to find a way to help her clients sleep better, and wanted to know if there is a significant difference in sleep quality based on the tidiness of one's room. To test this idea, she decided to administer a survey to 50 of her clients on their cleaning habits and sleep quality. Her clients were to classify their sleep either as poor, okay, or excellent. The observed frequencies are shown below.

Sleep Quality
Bedroom tidiness	Poor	Okay
Clean	5	8
Messy	11	7
