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 OC Ho p 0 20 H p 0 20 OE H P 0 80 H p 0 80 B Ho p 0 80 H p 0 80 OD Ho p 0 20 H p 0 20 OF 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 Identify the conclusion about the null hypothesis and the final conclusion that addresses the original claim Ho There sufficient evidence to support the claim that the polygraph results are correct less than 80 of the time
