Trials in an experiment with a polygraph include 96 results that include 23 cases of wrong results and 73 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 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 B. Ho P= 0.80 H, P#0.80 H, P 0.80 OF Hop=0.20 H, p> 0.20 The test statistic is z = (Round to two decimal places as needed ) Enter your answer in the answer box and then click Check An
