For his undergraduate capstone project, Jorge wants to determine if memory recall differs based on the color of the testing room. He plans to study a bright color (e. g., red), an earth tone (e. g., forest green), and a neutral color (off-white). Participants are randomly assigned to groups and there are 30 participants per group. Jorge is concerned that some participants might be assigned to a room that matches their color preference. For example, a person whose favorite color is red might be assigned to the red room. Jorge's advisor probably would reply that .
