  1. A screening test is applied to a population of 1,000 in which the prevalence of the disease in question is 10%. The sensitivity of this test is 96% and the specificity is 92%. The cost of screening the 1000 people is $50 (fifty dollars) per person. A newer screening test has the same sensitivity, a specificity of 96%, but costs $0.50 (fifty cents) more per test than the older screening test. For each person with a positive result from either test, a follow-up diagnostic test must be done that costs an additional $50 (fifty dollars).
    1. Calculate how much money would be saved or lost by choosing the newer screening test (1)?

Disease X has a low prevalence in population A, and high prevalence in population B. Which of the following is true? (2 points) The positive predictive value of a screening test will be higher in population B compared to population A.

The prevalence of a disease D in the population is 10%. A new test is introduced by a laboratory with the following characteristics. The laboratory notes that if someone has the disease, his or her test will be positive 90% of the time (P(pos|D) = 0.90). However, a completely healthy individual will test positive with probability 0.06 (P (pos|Dc) = .06).    (a) If we randomly select 5 people from this population, what is the probability that all of them...

In a screening program of 10,000 people, the disease prevalence was 1%. The sensitivity was 90.0% and the specificity was 99.0%.

The prevalence of undetected diabetes in a population to be screened is 1.5%, and it is assumed that 25,000 persons will be screened. The screening test will measure blood serum glucose content. A value of 180 mg or higher is considered positive. The sensitivity and specificity associated with this screening test are 22.9% and 99.8%, respectively. a. How many patients tested positive for diabetes according to the gold standard? b. How many patients are true positives? c. How many patients...
