**Polygraph Test Accuracy Analysis****Introduction:**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 Null and Alternative Hypotheses:**- **A.** - \( H_0 \): Polygraph testing is not accurate. - \( H_1 \): Polygraph testing is accurate.- **B.** - \( H_0 \): Whether a subject lies is independent of the polygraph test indication. - \( H_1 \): Whether a subject lies is not independent of the polygraph test indication.- **C.** - \( H_0 \): Whether a subject lies is not independent of the polygraph test indication. - \( H_1 \): Whether a subject lies is independent of the polygraph test indication.- **D.** - \( H_0 \): Polygraph testing is accurate. - \( H_1 \): Polygraph testing is not accurate.**More Info:**| Did the Subject Actually Lie? | No (Did Not Lie) | Yes (Lied) ||--------------------------------------------|------------------|------------|| Polygraph test indicated that the subject lied. | 8 | 32 || Polygraph test indicated that the subject did not lie. | 29 | 10 |**Instructions:**- Click the icon to view the table.- Use the information provided to select the appropriate null and alternative hypotheses.**Submission:**- Print or confirm your selection using the options below.**Options:**- **Print**- **Done** ### Title: Evaluating the Effectiveness of Polygraph Tests#### Introduction:The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subject lied or did not lie, so the table indicates whether 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?#### Instructions:Click the icon to view the table.#### Tasks:1. \(\chi^2\) (Round to three decimal places as needed): ___________2. Determine the P-value of the test statistic: - P-value = _________ (Round to four decimal places as needed) #### Discussion:Do the results suggest that polygraphs are effective in distinguishing between truth and lies?- **A.** There is not sufficient evidence to warrant rejection of the claim that whether a subject lies is independent of the polygraph test indication.- **B.** There is sufficient evidence to warrant rejection of the claim that polygraph testing is 95% accurate.- **C.** There is sufficient evidence to warrant rejection of the claim that whether a subject lies is independent of the polygraph test indication.- **D.** There is not sufficient evidence to warrant rejection of the claim that polygraph testing is 95% accurate.

Brown wants to conduct an assessment of where employees live and how employees work. Brown wanted to know if where you lived was related to how you worked. What hypothesis tests can be used in this case?
In the hypothesis testing procedure, a is 1 - level of significance. Select one:
Choose the correct answer.If the P-value of a test of significance is 0.999 then:A. the null hypothesis should be rejected.B. the null hypothesis should not be rejected.C. the alternative hypothesis provides a plausible explanation of the data.D. Both A and C are true.

Determine if the survey question is biased. If the question is biased, suggest a better wording. How often do you eat vegetables during an average month? Is the question biased? OA. Yes, because it does not lead the respondent to any particular answer. A better question would be "Why is eating vegetables good for you?" OB. Yes, because it influences the respondent into thinking that eating vegetables is good for you. A better question would be "Do you think that eating vegetables is good for you?" OC. No, because it influences the respondent into thinking that eating vegetables is good for you. OD. No, because it does not lead the respondent to any particular answer.

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.

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)
