The table below displays results from experiments with polygraph instruments. Find the positive predictive value for the test. That is, find the probability that the subject lied, given that the test yields a positive result Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) Positive test results Negative test results The probability is (Round to three decimal places as needed)
The table below displays results from experiments with polygraph instruments. Find the positive predictive value for the test. That is, find the probability that the subject lied, given that the test yields a positive result. Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) Positive test results 1515 4040 Negative test results 3030 1212 The probability is? (Round to three decimal places as needed.)
Use the sample data in the table. Results from Experiments with Polygraph Instruments Did the Subject Actually Lie? No Yes (Did Not (Lied) Lie) 15 42 (false (true positive) positive) Positive test result (Polygraph test indicated that the subject lied.) Negative test result (Polygraph test indicated that the subject did not 32 9 (true (false negative) negative) lie.) If 3 of the 98 test subjects are randomly selected without replacement, find the probability that they all had false positive results....
The table below displays results from experiments with polygraph instruments. Find the positive predictive value for the test. That is, find the probability that the subject lied, given that the test yields a positive result. The probability is _______ (Round to three decimal places as needed.)
The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? Click the icon to view the table. Determine...

12. Refer to the sample data for polygraph tests shown below. If one of the test subjects is randomly selected, what is the probability that the subject is not lying? Is the result close to the probability of 0.406 for a negative test result? _ No_(Did_Not_Lie) Yes_(Lied) Positive_test_results 16 44 Negative_test_results 27 14 The probability that a randomly selected polygraph test subject was not lying is___ (Type an integer or decimal rounded to three decimal places as needed.) 13.
