The owner of a new puppy wants to "house train" her pet. She reads a study where a researcher selected 15 puppies for training. Three training methods were used. Reinforcement with doggy treats (pleasure), spanking with newspaper (pain) and a combination of the two (combination). The study indicated that 10 of the puppies responded best to pleasure, 2 responded best to pain, and 3 responded best by combination. The researcher concludes that reinforcement by pleasure is, ingeneral, the best method for house training puppies. Set the problem up in formal statistical terms and determine whether or not the researcher is correct.
