Do hamsters preferred treats or blue treats? Two different supplements, which have
no effect on taste, are used on identical treats to produce a red treat or a blue treat.
Volunteer hamsters are randomly assigned to either a red treat or a blue treat, and the researchers rate the treats based on how quickly the hamsters eat them. Is blinding
demonstrated in the experiment? (4 points)

- No, because the hamsters do not know the color treat they are getting

- Yes, by having te experimenter in a separate room pick one of the two containers at random
and having a treat pulled from that container remotely

- No, because the hamsters know whether they are eating a red treat or a blue treat

- Yes, by having the statistician analyzing the results not know which hamster sampled which
treat

- Yes, by having the hamsters eat the treats out of the container, so they don't know the color of
the treat they are eating
