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 B. H,: p=0.20 O A. Ho: p=0.80 H;:p<0.80 H: p>0.20 OC. Ho: p=0.20 O D. H: p=0.20 H;: p<0.20 H;: p#0.20 OF. Ho: p=0.80 ОЕ. Н р0.80 H,: p*0.80 H,: p>0.80 The test statistic is z= (Round to two decimal places as needed.) The P-value is - (Round to four decimal places as needed.) Identify the conclusion about the null hypothesis and the final conclusion that addresses the original claim. V Hg. There v sufficient evidence to support the claim that the polygraph results are correct less than 80% of the time.
