Research question: Does consuming alcohol impact reaction times? A sample of 60 adults was obtained. All participants were at least 21 years old and were told that they would be drinking a beer before having their reaction times tested. Half of the participants were randomly selected to drink 12 ounces of alcoholic beer. The remaining half were given 12 ounces of non-alcoholic beer. Participants were not told that half of the beers were non-alcoholic. Use this scenario to answer the following questions. Please label each part of your answer (i.e., A, B). 1. Which group is the placebo group in this study? 2. Explain why it is important for this particular study to have a placebo group
