52. Question: A group of scientists want to know if drinking Dr. Pepper along with an antacid will cure a stomachache better than antacid alone. They think that the carbonation in the Dr. Pepper will cause the stomachache to go away faster. To find out, they give 50 patients VERY spicy food to make their stomachs hurt. Then, 25 of the patients get an antacid with water, and the other 25 patients get an antacid with Dr. Pepper. They then time how long it takes for the stomach aches to go away. On average, patients that got water and antacid quit hurting in 15 minutes, but patients that got Dr. Pepper and antacid took 25 minutes to feel better.
