Trials in an experiment with a polygraph include 99 results that include 22 cases of wrong results and 77 cases of correct results. Use a 0.01 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.   a. The test statistic is  z equals ​(Round to two decimal places as​ needed.)   b. The​ P-value is   ​(Round to four decimal places as​ needed.)

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. Ho: p=0.80 H₁: p=0.80 O B. Ho: p=0.20 H₁: p=0.20 O C. Ho: p=0.80 H₁: p > 0.80 O E. Ho: p=0.20 H₁: p0.20 OF. Ho: p=0.80 H₁: 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…
