In a study whose results were published in theBritish Medical Journal (Willis et al., 2004), researchers tested whether dogs can smell cancer in humans. Each dog used in the study was presented with seven urine samples to smell, with only one of the urine samples coming from a patient who had bladder cancer. Taken as a group, the dogs were tested on 54 trials and correctly identified the urine from the cancer patient in 22 trials. If the dogs were just guessing and so had a probability of successp= 1/7, what is the probability they would be correct in 22 or more of the 54 trials?
