Question:
A dog food company wants to compare a new lower-calorie food with their standard dog food to see if it's effective in helping inactive dogs maintain a healthy weight. They have found 10 dog owners willing to participate in the trial. They have randomly selected five of the dog owners to feed their dogs the standard food, and the other five dog owners will feed their dogs the new lower-calorie food. The owners have agreed not to feed their dogs anything else for a period of six months, after which the dogs' weight will be checked.
