Multiple Choice

Diagnostic tests of medical conditions have several results. The rest result can be positive or negative. A positive test (+) indicates the patient has the condition. A negative test (-) indicates the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 131 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown.4 Assume that the sample is representative of the entire population. For a person selected at random, find P() . Round your answer to the nearest hundredth.
$$\begin{array} { l c c r } & \text { Condition Present } & \text { Condition Absent } & \text { Row Total } \\\text { Test Result } + & 115&16&131 \\\text { Test Result } - & 16&60&76 \\\text { Column Total } & 131&76&207\\\end{array}$$ $$\text { Condition present|getting test result } +$$
