Homework Answers
The use of lie-detector tests has been outlawed by the federal government and reasonably so. These tests have huge potential for misuse and even abuse of a prospective employee's private information. In the past, there have been instances of employees and applicants being presented with questions about extremely private matters, such as religious beliefs, sexual preference, racial matters, lawful activities of labor organizations, and political affiliation. Most of these sensitive topics have little to do with a prospective employee's professional life.

A study was done on the effectiveness of lie detector tests to catch someone that lies. In a random sample of 48 total lies, the machine identified only 31 of them. What was the sample percentage? Now construct a 99% confidence interval estimate of the population percentage of lies caught by the lie detector machine.

Polygraph lie-detector machines are commonly used in criminal investigations. The device measures nervous excitement, operating on the idea that if a person is telling the truth they will remain calm. The American Polygraph Association claims that polygraphs accurately identify liars 90% of the time. In other words, if a person lied the test results will be positive 90% of the time. Although the polygraph test is good at identifying liars, there is a 50% chance that the polygraph test will...

A polygraph (lie detector) is an instrument used to determine if an individual is telling the truth. These tests are considered to be 92% reliable. In other words, if an individual lies, there is a 0.92 probability that the test will detect a lie. Let there also be a 0.080 probability that the test erroneously detects a lie even when the individual is actually telling the truth. Consider the null hypothesis, "the individual is telling the truth," to answer the...

No Lie MRI No Lie MRI is a San Diego-based company offering state- of-the-art brain-scan lie detection services, using a technology called functional magnetic resonance imaging (or FMRI). No Lie MRI believes that neuroscience-and specifically, fMRI technology-will reshape forensic science and courtroom pro- cedures. Old-fashioned polygraph lie detector tests are only moderately accurate; with fMRI technology, you can essentially peer inside a person's mind and see what he or she is thinking You can "see" who is telling the truth...

Question Help Lie detectors are controversial instruments, barred from use as evidence in many courts. Nonetheless, many employers use lle detector screening as part of their hiring process. There has been some research, but no agreement, about the reliability of polygraph tests. Based on this research, suppose that a polygraph can detect 62% of lies, but incorrectly identifies 11% of true statements as lies. A company believes that 96% of its job applicants are trustworthy. The company gives everyone a...

Now that you have learned a bit about how Amazon uses A/B tests, what do you think are some of the risks and challenges associated with performing so many hypothesis tests? What would you do to mitigate those risks? Think about the results of the tests. What were the effects? Look at the size of the effects. Were they small or large? Why were the sample sizes so large?

Forcing employees to take tests to reveal whether...

Polygraph tests have an accuracy rate of about 90%. This means that it will detect 90% of people who lie and 90% of people who are telling the truth. A company of 5000 employees has everyone submit to a polygraph test. It turns out there are 50 employees who will lie during their polygraph. (Hint: Tests Positive means they are lying!)
