  1. You are evaluating a non-destructive test for a defect. The prevalence of the defect in a random sample of your product is 1%. If a sample has the defect, the test will be positive 99% of the time. If a sample does not have the defect, the test will be negative 99% of the time. What is the probability that a sample has a defect given that the test is positive? NEED explanation, please

The prevalence of a disease D among the population is 3%. There is a diagnostic test for disease D. The sensitivity of this test is 99%, this means that the test is positive given that the person has the disease. The specificity of this test is 98%, this means that the test is negative given that the person does not have the disease. a) Given that a person tests positive, what is the probability that the person does not have...

Suppose 1% of a given population have a certain genetic defect. For a new gene test, it gives a positive result with 90% probability when an individual does have the genetic defect, and it gives a positive result with 9.6% probability when an individual does NOT have the genetic defect. a. If a person gets a positive test result, what is the probability that he/she actually has the genetic defect? If a person gets a negative test result, what is...

5. In medical tests the prevalence of a disease in a given population is the percentage of the population that has the disease. For a population with a known prevalence, the positive predictive value (PPV) of a test is the probability that a person in the population that tests positive actually has the disease. The negative predictive value (NPV) of a test is the probability that a person in the population who tests negative, in fact, does not have the...

Suppose 1 in 25 adults is afflicted with a disease for which a new diagnostic test has been developed. Given that an individual actually has the disease, a positive test result will occur with probability .99. Given that an individual does not have the disease, a negative test result will occur with probability .98. Use a probability tree to answer the following questions. Question 1. What is the probability of a positive test rest result? Question 2. If a randomly...

1. In a destructive test of product quality, a briefcase manufacturer places each of a simple random sample of the day’s production in a viselike device and measures how many pounds it takes to crush the case. From past experience, the standard deviation has been found to be 21.5 pounds. For 35 cases randomly selected from today’s production, the average breaking strength was 341.0 pounds. The lower confidence limit of 99% confidence interval for the mean breaking strength of the...

Mammograms are a relatively inexpensive and nonintrusive way to test for breast cancer. Suppose that mammogram screenings are 93% specific and 87% sensitive. This means that those without breast cancer test negative 93% of the time and those with breast cancer test positive 87% of the time. Answer the following questions as if 12.6% of all women have breast cancer. a) Given that a women tests negative, what is the probability that she has breast cancer? (b) Given that a...

1) The reliability of a particular skin test for tuberculosis (TB) is as follows: the sensitivity of the test is 0.9 (the test comes back positive 90% of the time if the subject has TB) and the specificity of the test is 0.95 (if the subject does not have TB, the test comes back negative 95% of the time). In a large population, only 0.3% (0.003) of the people have TB. A person is selected at random and given the...

Sensitivity and specificity essential characteristics of medical tests. Sensitivity is the probability that the test will indicate “disease” given that the individual actually has the disease, and specificity is the probability that the test will indicate “no disease” given that the individual does not have the disease. Answer the following questions for a test with sensitivity 75% and specificity 99%. Let p denote the prevalence of the disease (i.e., proportion of the population with the disease). (a) For p =...

For disease X, there’s a new rapid and accurate test in the market. The sensitivity of the test is 90% (probability to correctly detect disease X with positive test result), and the specificity of the test is 99% (probability to correctly give negative result for disease X free case). The prevalence of the disease is 0.01% in the population. Write in as percentage without percentage sign and with three decimal places. What is Pr[ X | positive ]? (i.e. probability...
