Trials in an experiment with a polygraph include 96 results that include 22 cases of wrong results and 74 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 Oc. H p=0.20 H p 0.20 O B. H p=0.20 H. p<0.20 OD. H p= 0.80 H p> 0.80 O E. Ho p= 0.20 Hr p>0.20 OF. 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 final conclusion that addresses the original claim. Ho. There M sufficient evidence to support the claim that the polygraph results are correct less than 80% of the time. Fail to reject Reject
