Trials in an experiment with a polygraph include 07 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. Ho: p-0.80 H;: p>0.80 O B. Họ: p-0.20 H: p> 0.20 Ос. На ра0.20 H: p0.20 O D. Ho: p-0.80 H: p0.80 O E. Ho: p-0.80 H4: p«0.80 OF. Ho: p=0.20 H,: p«0.20
