Question

Refer to the table which summarizes the results of testing for a certain disease. If one of the results is randomly selected, what is the probability that it is a false positive (test indicates the person has the disease when in fact they don't)? Round the probability to three decimal places. What does this probability suggest about the accuracy of the test? 0.149; The probability of this error is high so the test is not very accurate. 0.399; The probability of this error is high so the test is not very accurate. 0.101; The probability of this error is high so the test is not very accurate. 0.026; The probability of this error is low so the test is fairly accurate. Sample tests and quizzes can be taken for practice or to build your study plan. Sample tests and quizzes do not affect your grade.

Explanation / Answer

total number of results =80+27+7+154=268

out of which false +ve =27

hence probability =27/268=0.101
