Do teenagers prefer yellow candy or pink candy? Two different supplements, which have no effect on taste, are used on identical
candies to produce a yellow or pink candy. Volunteer teenagers are randomly assigned to either pink candy or yellow candy. The
participants are then asked to rate the candy on a 1- to 10-point scale. Is blinding demonstrated in this experiment?
A. No, because the volunteers do not know the color candy they are getting
B. No, because the volunteers know whether they are eating yellow candy or pink candy
C. Yes, by having the experimenter in a separate room pick one of the two containers at random and having a candy pulled
from that container remotely
D. Yes, by having the statistician analyzing the results not know which volunteer sampled which candy
E. Yes, by having the volunteers wear a blindfold while they eat the candy out of the container so they don't know the color of
the candy they are tasting
