Researchers have been studying the reliability of a new medical test. On their last study, they found that the test accurately identified those with the disease 92% of the time, and it accurately identified those without the disease only 74% of the time. There were 1,000 total people in this study, and 200 of them had the disease. Complete the table below using this information. Then, use your completed table to help you answer the questions.
