2. Hypotheses Refer to the data given in Exercise 1 and assume that the requirements are al satisfied and we want to conduct a hypothesis test of independence using the methods of thi section. Identify the null and alternative hypotheses. 3. Hypothesis Test The accompanying TI-83/84 Plus calculator display results from th hypothesis test described in Exercise 1. Assume that the hypothesis test requirements are a satisfied. Identify the test statistic and the P-value (expressed in standard form and rounded t three decimal places), and then state the conclusion about the null hypothesis. 4. Right-Tailed, Left-Tailed, Two-Tailed Is the hypothesis test described in Exercise 1 righ tailed, left-tailed, or two-tailed? Explain your choice.

In Exercises 5-18, test the given claim.
5. Lie Detector The table below includes results from polygraph (lie detector) experiments
conducted by researchers Charles R. Honts (Boise State University) and Gordon H. Barland
(Department of Defense Polygraph Institute). In each case, it was known if the subject 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 truths and lies?
Notifications
Did the Subject Actually Lie?
No (Did Not Lie)
