Trials in an experiment with a polygraph include 97 results that include 24 cases of wrong results and 73 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 OA. Ho: p=0.20 H: p 0.20 OE H p=0.80 H: p>0.80 The test statistic is z= -1.17. (Round to two decimal places as needed.) The P-value is 0.1210 (Round to four decimal places as needed.) B. Ho p=0.80 H: p
