Information
Use the following information to answer the next 3 problems.
Human blood can be classified into one of our basic types: O, A, B, and AB. The proportion of people in
the population of the United States with each of these blood types is summarized in the following table
[1]:
Question 3 point

Use the following information to answer the next 2 questions.
Carolyn Willis and her colleagues conducted a study in which dogs were trained to detect bladder cancer.
The dogs were trained to lie down next to a specimen derived from a bladder cancer patient. Tangle, one
of the dogs, demonstrates the identification of a specimen. Seven bowls containing urine were lined up in
a random order. Six of the samples were from patients who did not have bladder cancer. One of the
samples came from a person identified as a bladder cancer patient.
Question 6 point
If the dogs guess at random, what is the probability that they will correctly identify the dish containing the
specimen from the bladder cancer patient? (round answer to three decimal places)
Answer:
0.143
Question 1/1
7 point
In a combined total of 54 trials, the dogs correctly identified the specimen from the cancer patient 22
times. It is very unlikely that the dog would do this well by random chance alone. Which of the following
statements is most appropriate?
