Question 8 (1 point) Suppose we choose one of these breath specimens at random. What is the probability that we get one of the control subjects in the experiment? Give a percent answer out to two decimal places (that is, xx.xx%) Research has shown that specific biochemical markers are found exclusively in the breath of patients with lung cancer. However, no lab test can currently distinguish the breath of lung cancer patients from that of other subjects. Could dogs be trained to identify these markers in specimens of human breath, as they can be to detect illegal substances or to follow a person's scent? An experiment trained dogs to distinguish breath specimens of lung cancer patients from breath specimens of control individuals by using a food-reward training method. After the training was complete, the dogs were tested on new breath specimens without any reward or clue using a double-blind, completely randomized design. Here are the results for a random sample of 1286 breath specimens: Breath Specimen Dog Test Control Cancer Total Subject Subject Negative Positive 4 564 568 Total
