Sore throat and cold - To control the spread of COVID-19 it is critical to quickly identify and quarantine individuals who may have the illness. Since it is difficult to medically test everyone in a population, researchers have identified a list of self-reported symptoms that could be used to identify patients who need to receive a medical test for COVID-19. From a study conducted during the first year of the COVID-19 pandemic, researchers found that among the people who got positive results from a nasopharyngeal swab (NPS) COVID test, 33.4% of them experienced sore throat and cold. On the other hand, the symptom was experienced by 37.6% of people who got negative results from a NPS test. Suppose that the percentage of people testing positive in Singapore is 8%. Use this value as a base rate and a theoretical population of 10,000 people living in Singapore to complete the contingency table. Use the table to answer the following questions. Give all answers to 4 decimal places. Test result NPS test is positive NPS test is negative Total Person reports sore throat and cold Person does not report sore throat and cold Total 10,000 1. What proportion of people living in Singapore would we expect not to report sore throat and cold? 2. What proportion of people living in Singapore who report sore throat and cold would we expect to have a negative result from an NPS test? 3. What proportion of people living in Singapore who do not report sore throat and cold would we expect to have a positive result from an NPS test?
