Bladder Cancer Statistics

Question: Hypothesis testing with Statistics.There is 6 samples of urine from health people and one with bladder cancer.? Dogs were trained to pick out the cancer sample. The trial was repeated 54 times with 22 correct identifications and 32 incorrect. What is the probability that a dog would select the cancer sample?

Answer: If the dogs get it right 22 out of 54 times with the sample data, then it looks like the probability is 22/54 = 11/27. Which is better than random chance.
