Jesse was starting a new workout at his gym. His trainer was conducting an assessment where he needed to determine at which point Jesse could tell the difference in weight between two different dumbbells. Jesse was unaware of the weights being placed in his hands. The trainer started by placing a 10 lb dumbbell in each hand. Jesse said they felt the same. His trainer increased one dumbbell to 11 lbs but Jesse still said they felt the same. It was not until he was holding one 12 lb weight and one 10 lb weight where he could reliably (50 percent of the time) determine which weight was heavier. The next day, his trainer did the same exercise, but this time he started with 20 lb dumbbells. What will one of the dumbbells have to weight in order for Jesse to reliably be able to detect a difference?
