Use Excel to find the probability round your answer to three decimal places
- Question: Alex wants to test the reliability of “lie detector test” 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 test result is no false positives. Alex will conclude that the test 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 3 decimal places.

- Question: Alex wants to test the reliability of “lie detector teste” 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 test does not result in a true statement being … as 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.?
