The table below includes resuts from polygraph (lie dotector) 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 005 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? FE Click the icon to view the table. O A. H Polygraph testing is accurate.
