Students were blindfolded and then given a red-colored or yellow-colored candy to chew. (Half the students were assigned to receive the red candy and half to receive the yellow candy. The students could not see what color candy they were given.) After chewing, the students were asked to guess the color of the candy based on the flavor. Of the 130 students who participated in the study, 95 correctly identified the color of the candy. The results are shown in the accompanying technology printout. Complete parts a through c below.
