A study investigates whether the color of a plate affects how much food people eat. 120120 participants are randomly assigned to eat a meal from either a red plate or a blue plate in the first session. In the second session, they switch to the other color. The order of plate color is randomly assigned for each participant. Explain the role of randomization in this experiment.

Randomization helps ensure that any observed differences in food consumption are due to plate color and not other factors

Randomization prevents participants from knowing which plate color they will get

Randomization guarantees that everyone eats the same amount

Randomization makes the experiment faster to conduct
