Using the data found in Table 4 and Bayes’ Formula, determinethe probability that a randomly selected patient will have StrepThroat given the SARTD test result was positive. Use the CDC statedprevalence of 25%. Round answer to nearest hundredth of a percent(i.e. 45.67%).
Then using the same Table 4, and Bayes’ Formula, determine theprobability that a randomly selected patient will not have StrepThroat given the SARTD test result was negative. Use the CDC statedprevalence of 25%. Round answer to nearest hundredth of apercent.
| Strep Pos | Strep Neg | Total |
| SARTD Pos | 80 | 23 | 103 |
| SARTD Neg | 38 | 349 | 387 |
| Total | 118 | 372 | 490 |
