Trials in an experiment with a polygraph include 98 results that include 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. 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 O B. Ho: P= 0.20 H,: P 0.20 O E. Ho: P= 0.80 OF. Ho: P= 0.80 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. Ho. There V sufficient evidence to support the claim that the polygraph results are correct less than 80% of the time
