From given table,
Total = 67 + 11 + 12 + 102 = 192
The probability of a false negative
= 102 / 192
= 0.53

For Questions 22 through 24, please refer to the following scenario. A new screening test for Lyme disease is developed for use in the general population. The sensitivity and specificity of the new test are 60% and 70%, respectively. Three hundred patients are screened at a clinic during the first year the new test is implemented. The prevalence of Lyme disease among clinic patients is 10%. Gold Standard diagnosis Disease Yes Disease No Total ScreeningPositive Negative 22. (3 points) Fill...
Diabetes Screening Shown below are the real-life diagnostic characteristics of a particular diabetes-screening test – a fasting venous glucose measurement – from a hypothetical cross-sectional study population. Calculate the sensitivity, specificity and positive predictive value (PPV) of this screening test and estimate the prevalence of diabetes in the study population. Table: Results of fasting venous glucose screening for diabetes. Diabetes Screening Test Actual diabetes status Total Present Absent Positive (+) True + 67 False + 38 Total + 105 Negative...
A screening test for a rare from of TB has a 7% false positive rate (i.e. indicates the presence of the disease in people who do not have it). The test has an 18% false negative rate (i.e. indicates the absence of the disease in people who do have it). Suppose that 3% of the population have the disease. (i) Partition the sample space into those who have the disease, B1, and those who don’t have the disease, B2. Find...
A screening test for a rare form of TB has a 7% false positive rate (i.e. indicates the presence of the disease in people who do not have it). The test has an 8% false negative rate (i.e. indicates the absence of the disease in people who do have it). In a population of which 0.6% have the disease, what is the probability that someone who tests positive has the disease?
