Trials in an experiment with a polygraph include 97 results that include 24 cases of wrong results and 73 cases of correct results. Use a 0.05 significance level to test the claim that such polygraph results are correct less than 80% of the time. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. .. Let p be the population proportion of correct polygraph results. Identify the null and alternative hypotheses. Choose the correct answer below. O A. H, p= 0.80 H,: p 0.80 O B. H,: p= 0.20 H,: p> 0.20 O C. H, p= 0.20 H,: p<0.20 D. H,: p= 0.80 H,: p<0.80 O E. H, p= 0.80 H;: p> 0.80 OF. H,: p= 0.20 H,: p#0.20 The test statistic is z= - 1.17. (Round to two decimal places as needed.) The P-value is (Round to four decimal places as needed.)

Transcribed Image Text:Trials in an experiment with a polygraph include 97 results that include 24 cases of wrong results and 73 cases of correct results. Use a 0.05 significance level to
test the claim that such polygraph results are correct less than 80% of the time. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion
about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the
binomial distribution.
