The table includes results from the polygraph experiments. In which case, it was known if the subject line or not, 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 you the results suggest that polygraphs are effective in distinguishing between truths and lies?
