1. Dr. Wallace conducted a large-scale study by computing the average GPA of Health Sciences students and comparing it with the average GPA of Medical students from 300 universities in California. He also conducted another analysis and computed the average broccoli intake for all of CA university students and compared between Medical and Health Sciences students. He hypothesized that the intake of broccoli is associated with higher GPA. The study findings are displayed in the table below. Based on these findings, Dr. Wallace concluded that, indeed, broccoli intake is associated with a higher GPA (3 pts).

	Health Sciences	Medicine
Average GPA	3.7	3.4
Intake of Broccoli Cups/day	5 cups	2 cups
