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 polygrap test indication.
