Question
The table below includes results from polygraph (lie detector) 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 0.05 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 ies? Click the icon to view the table. Determine the null and aternative hypotheses. 0 A. Ho: Polygraph testing is accurate. O B. Ho: Polygraph testing is not accurate. C. Ho: whether a subject lies is independent of the polygrah lest indication. O D.
