P VALUE FOR TEST HYPOTHESIS

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 0.05 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. OA. Ho: p=0.80 H₁: p > 0.80 O C. Ho: p=0.20 H₁: p>0.20 E. Ho: p=0.20 H₁: p0.20 The test statistic is z = . (Round to two decimal places as needed.) B. Ho: p=0.80 H₁: p=0.80 D. Ho: p=0.20 H₁: p<0.20 F. Ho: p=0.80 H₁: p<0.80
