Alex wants to test the reliability of "lie detector tests," or polygraph tests. He performs a polygraph test on a random sample of 12 individuals. If there is more than a 50% chance that the tests result in no false positives (that is, the tes does not result in a true statement being recorded as a lie), Alex will conclude that the tests are reliable. If the probability of a lie detector test resulting in a false positive is 5.5%, what will Alex conclude? Use Excel to find the probability, rounding to three decimal places. Select the correct answer below: Alex will conclude that the test is reliable since the probability of no false positives is less than 0.5. O Alex will conclude that the test is not reliable since the probability of no false positives is greater than 0.5. O Alex will.conclude that the test is not reliable since the probability of no false positives is less than 0.5. O Alex will conclude that the test is reliable since the probability of no false positives is greater than 0.5.
