It is estimated that 1% of all people have a particular disease. The test for this disease has a false positive rate of 2%, and a false negative rate of 3%.
1. Draw a tree diagram for this experiment.
2. Suppose that a person is selected at random and tested. Given that the test is negative, what is probability that the person does not have the disease?

it is estimated that 40% of all sharks have a particular disease. Suppose a test for the disease has been developed - it has a false positive rate of 10% and a false negative rate of 5%. i) calculate the probability that a randomly selected shark will test positive for the disease. ii) if a shark tests positive for the disease, what is the probability that the shark actually has the disease?

In a laboratory, blood test is 95% effective in detecting a certain disease, when it is, in fact, present. However, the test also yields a false positive (test is positive but patient does not have the disease) result for 1% of the healthy people tested. 0.5% of the population actually has the disease. Given this information, calculate the following probabilities: The probability that the test is positive. Given a negative result, the probability that the person does not have the...

[Base Rate Fallacy] Suppose a particular disease has a prevalence of 0.5 % people. A medical test to detect this disease has a false-positive rate of 5 % and diagnoses correctly every person who has the disease. What is the probability that a randomly selected person found to have a positive result actually has the disease? Give your answer to three decimal places.

A disease affects 16% of the population. There is a test (not perfect) that detects disease with a probability of 98% (i.e comes back positive when the person has the disease). However, the test produces 5% false positives, i.e comes back positive even though the person does not have the disease. i) A person who has the disease is tested, what is the probability that the test will come back negative. ii) What is the probability that a randomly selected...

Consider a small town that has a population of 1,000 people. It is known that in this town, 10 people are infected with a rare disease. The remaining 990 people are NOT infected with the disease. This data is known with certainty. Recently, The FDA (Food and Drug administration) developed a test that determines if a person is infected with this disease. However, as with most test of this nature, it is not foolproof proof as there are a certain...

3. The reliability of a particular test for the Eboli dorty of a particular test for the Ebola virus is as follows: If the subject has Ebola, ne test comes back positive 98% of the time. If the subject does not have Ebola, the test comes back negative 99% of the time. In Michigan, 2 in every 10.000 people have Ebola. (a) What the probability of False Positive and False Negative in the Ebola test. Draw a Venn diagram to...

3. Assume 6% of people have a certain disease. A test gives correct diagnosis with probability 0.85 i.e. if the person is sick, the test will be positive with probability 0.85, but if the person is not sick, the test will be positive with probability 0.15. A random person from the population has tested positive for the disease. What is the probability that he is actually sick? Part 2. Random Variables

Suppose that the people attending a resort have a long-term chance of 1 in 100 of having skin cancer (from too much sun exposure). The resort maintains a clinic to help detect this disease. Suppose that the screening used at this clinic has a false positive rate of 0.2 (that is 20% of people without skin cancer will test positive for cancer) and that it has a false negative rate of 0.1 (10% of people with skin cancer will test...

3. One half percent of the population has a particular disease. A test is developed for the disease. The test gives a false positive 3% of the time and a false negative 2% of the time. a. [7] What is the probability that Joe (a random person) tests positive? b. [6] Joe just got the bad news that the test came back positive; what is the probability that Joe has the disease?
