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 lies Click the icon to view the table Determine the null and alternative hypotheses OA Ho Polygraph testing is accurate H Polygraph testing is not accurate OB Ho Whether a subject lies is not independent of the polygraph test indication H Whether a subject lies is independent of the polygraph test indication O Ho Whether a subject lies is independent of the polygraph test indication H Whether a subject lies is not independent of the polygraph test indication Ho Polygraph testing is not accurate H Polygraph testing is accurate M Determine the test statistic x 9 925 Round to three decimal places as needed Determine the P value of the test statistic P value 0 0016 Round to four decimal places as needed Do the results suggest that polygraphs are effective in distinguishing between truth and lies OA There is sufficient evidence to warrant rejection of the claim that whether a subject lies is independent of the polygraph test indication OB There is sufficient evidence to warrant rejection of the claim that polygraph testing is 95 accurate ufficient evidence to warrant rejection of the claim that whether a subject lies is independent of the polygraph test indication 05 Sourate
