Trials in an experiment with a polygraph include 97 results that include 22 cases of wrong results and 75 cases of correct results. Use a 0.01 significance level to t 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 ab 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 binomia 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 H,: p>0.80 B. Ho: p= 0.80 H,:p<0.80 O C. Ho: p=0.20 H,: p#0.20 O D. Ho: p=0.20 H,: p<0.20 O E. Ho: p=0.80 OF. Ho: p=0.20 H,: p>0.20 H,: p#0.80 The test statistic is = . (Round to two decimal places as needed.)

Question
Trials in an experiment with a polygraph include 97 results that include 22 cases of wrong results and 75 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.
O A. Ho: p=0.80
H,: p> 0.80
B. Ho:p=0.80
H,: p<0.80
OC. Ho: p=0.20
H;:p#0.20
O D. Ho: p= 0.20
H,: p<0.20
OF. Ho:p=0.20
O E. Ho: p=0.80
H,: p#0.80
H;: p>0.20
The test statistic is z =
