Can choosing the right music make wine taste better? This question was investigated by a researcher at a university in Edinburgh. † Each of 250 volunteers was assigned at random to one of five rooms where they were asked to taste and rate a glass of wine. In one of the rooms, no music was playing and a different style of music was playing in each of the other four rooms. The researchers concluded that cabernet sauvignon is perceived as being richer and more robust when bold music is played than when no music is heard. (a) Is the study described an observational study or an experiment? O an observational study O an experiment (b) Can a case be made for the researcher's conclusion that the music played was the cause for the higher rating? Explain. O Yes, since the participants were randomly assigned to the treatments the researcher can reasonably claim that the music played was the cause of the higher rating. O No, since we don't know if all of the participants like wine or not. O Yes, since the participants were in multiple rooms the researcher can reasonably claim that the music played was the cause of the higher rating. O No, since the participants could have walked to a different room or tried different glasses of wine we cannot reasonably claim that the music was the cause for the higher rating.
