9.) Trials in an experiment with a polygraph include 98 results that include 22 cases of wrong results and 76 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.

Let p be the population proportion of correct polygraph results. Identify the null and alternative hypotheses. Choose the correct answer below. 0 A. H0: p=0.20 H1: p0.20 The test statistic is z = D. (Round to two decimal places as needed.) The P-value is D. (Round to four decimal places as needed.) Identify the conclusion about the null hypothesis and the nal conclusion that addresses the original claim. OB. OD. H0: p=0.80 H1: p0.80 Ho: p=0.80 H1: p0.80 |:| H0. There |::| sufcient evidence to support the claim that the polygraph results are correct less than 80% of the time
