The table below includes results from polygraph(lie detector) experiments conducted by researchers. In eachcase, it was known if the subjected lied or did notlie, 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 andlies?

Determine the null and alternative hypotheses.

A.

H0: Whether a subject lies is independent of the polygraph test indication.

H1: Whether a subject lies is not independent of the polygraph test indication.

B.

H0: Polygraph testing is accurate.

H1: Polygraph testing is not accurate.

C.

H0: Whether a subject lies is not independent of the polygraph test indication.

H1: Whether a subject lies is independent of the polygraph test indication.

D.

H0: Polygraph testing is not accurate.

H1: Polygraph testing is accurate.
