13. 21. The new test was used in several other populations with varying disease prevalence. The table below shows those results. The population that you examined on p. 5-6 has not been filled in yet. Copy your answers from p. 5-6 questions 13, 17, 18, 19, and 20, into the correspondingly numbered cells of the table. (1 pt) Prevalence Positive Predictive False Discovery Rate Negative Predictive False Omission Rate Value Value 2% 28.36% 71.64% 99.94% 0.06% 17. 18. 19. 20. 14% 75.95% 24.05% 99.49% 95.10% 4.90% 96.94% 0.51% 3.06% 50% Answer the following questions in complete sentences. Mention specific column names and/or values to support your conclusions. 22. As the disease prevalence in a population increases, does the false discovery rate increase or decrease? Explain. (2 pts) 23. Is a positive result more likely to be true when the prevalence is high or low? Explain. (3 pts) 24. When a disease is rare in the general population, doctors are not likely to test everyone. Instead, they only test people that have specific risk factors or show symptoms of the disease. Even if resources are available, why do you think doctors would avoid giving a test for a rare disease to everyone in the general population? Explain using ideas from probability that were explored in this project. (5 pts) 13. 21. The new test was used in several other populations with varying disease prevalence.
