= The table to the right includes results from polygraph experiments. In each case, it was known if the subject lied or not, 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? Polygraph indicated that subject lied Polygraph indicated that subject did not lie Did the subject actually lie? No (did not lie) Yes (lied) 15 45 32 9 State the null and the alternative hypotheses. Choose the correct answer below. A. Ho: The row and column variables are independent. H: The row and column variables are dependent. OB. Ho: The row and column variables are dependent. Ha: The row and column variables are independent. OC. Ho: All values in the table are equal. H: At least one of the values is different from the others. D. Ho: At least one of the values is different from the others. Ha: All values in the table are equal. Find the value of the test statistic. The test statistic is . (Round to two decimal places as needed.)
