A researcher recruited 40 adults at a PTA meeting and asked them to view a video. To thank them for their participation, 20 adults were given a one-pound bag of M&Ms and the other half a half pound. All were told that they can snack on the M&Ms while they watched the video. The numbers of M&Ms eaten was recorded. Is there sufficient evidence to conclude that more M&M’s would be eaten by people who were given the full pound?
