Trials in an experiment with a polygraph include 99 results that include 24 cases of wrong results and 75 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. OA. Ho p=0.80 B. H p=0.80 H:p<0.80 H,: p#0.80 OC. Ho p=0.20 H;: p<0.20 OE. Ho p=0.20 H p>0.20 OD. Ho: p=0.20 H;: p#0.20 OF. H: p= 0:80 H;:p>0.80 The test statistic is z= (Round to two decimal places as needed.)
