Radon is a carcinogenic gas found in some types of soils that can build up in basements with poor ventilation. Detectors that monitor radon levels over a longer period are more accurate, but take longer for results to be available. The following table lists the results of a study that used both short- and long-term detectors. Long-Term Detector Long-Term Detector Short-Term Detector Positive Test result Negative Test Result Positive test result 44 53 Negative test result 23 61 a) What is the test sensitivity? This is the probability of a positive long-term result (true positive) GIVEN a positive short-term result. Number Round to 3 decimal places b) What is the test specificity? This is the probability of a negative long-term result (true negative) GIVEN a negative short-term result Number Round to 3 decimal places. c) If one of the results is randomly selected, what is the probability that it had a negative result on either the short-term or long-term detector? Number Round to 3 decimal places
