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? E Click the icon to view the table. Determine the null and alternative hypotheses. O A. Ho: Whether a subject lies is independent of the polygraph test indication. H1: Whether a subject lies is not independent of the polygraph test indication. O B. Ho: Polygraph testing is not accurate. H1: Polygraph testing is accurate. O C. Ho: Polygraph testing is accurate. H1: Polygraph testing is not accurate. O D. Ho: Whether a subject lies is not independent of the polygraph test indication. H1: Whether a subject lies is independent of the polygraph test…

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned.   Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.”    Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations.   1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.

When asked the question, "Do you believe Big Foot exists," out of 3,268 responses, 51.4% were "yes."  Using a 0.05 significance level to test a claim that most people believe in Big Foot, a P-value of 0.0466 is found.  State the initial conclusion and the final conclusion of the claim.
