A clinic tests patients for the novel Zombie virus. A patient is likely to be tested positive with probability 0.25. If each patient testing is independent, answer the questions below: 1.Say the clinic has 30 treatment packets that it gives out to positively tested patients. What is the probability that the clinic tests 100 patients until it exhausts all of its 30 treatment packets?

A hospital is testing patients for a certain disease. If a patient has the disease, the test is designed to return a "positive" result. If a patient does not have the disease, the test should return a "negative" result. No test is perfect though. 90% of patients who have the disease will test positive. 10% of patients who don’t have the disease will also test positive. 20% of the population in question has the disease. If a random patient tests...

A test kit for a certain disease whose base risk is at 0.005 is under development. The kit is expected to yield the same true-positive rate as its true-negative rate, which both are referred to as accuracy rate (call it ?). Define an authentic positive case as an incidence where given a patient tested positive, they actually have the disease. a. If the accuracy rate of the kit is 0.95, what is the probability for an authentic positive case? b....

In a pandemic respiratory infectious disease caused by a virus A, the diagnostic test has been developed and carried out. Under this test when an individual actually has the disease with a positive result (true-positive test) occurs with the probability of 0.99, whereas an individual without the disease will show a positive test result (false-positive test) with the probability of 0.02. What is more, scientists have shown that 1 out of 1000 adults is confirmed positive and has this disease....

A drive through at the Mt. Nittany Medical Center tests patients in their car for COVID 19. They have found that 15% of the patients who are tested for COVID 19 test positive for the disease; the remaining patients test negative. Use this information to answer the following questions. 1.If 20 patients are tested, what is the probability that three of them test positive? (Use 4 decimal places) 2.Let X = # of patients who test positive for COVID 19...

6. Normal cytokine count for non disease carrying patients are found to be distributed normally with a mean and standard deviation of 55 and 10 respectively. If a patient is found to have a cytokine count below two standard deviations from the mean (<35) they are declared disease positive.1 Unbeknownst to anyone (except you), disease carrying patients have a normally distributed cytokine count with mean and standard deviation of 20 and 10 respectively .i) What proportion of disease carrying patients...

Suppose that a certain disease is present in 10% of the population, and that there is a screening test designed to detect this disease if present. The test does not always work perfectly. Sometimes the test is negative when the disease is present, and sometimes it is positive when the disease is absent. The following table shows the proportion of times that the test produces various results. Test Is Positive (P) Test Is Negative (N) Disease Present (D) 0.06 0.04...

To determine whether or not they have a certain disease, 160 people are to have their blood tested. However, rather than testing each individual separately, it has been decided first to group the people in groups of 10. The blood samples of the 10 people in each group will be pooled and analyzed together. If the test is negative. one test will suffice for the 10 people (we are assuming that the pooled test will be positive if and only...
