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? Determine the test statistic. (Round ofd to 3 decimal places) Find the P-Value What is the conclusion? (In case you are using excel, I will appreciate if you explain the steps of finding the test statistic and the P-value....But this is not a must)
