Trials in an experiment with a polygraph include 98 results that include 23 cases of wrong results and 75 cases of correct results. Use a 0.05 significance level to test the claim that such polygraph results are corect 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.
Question Help v
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=0.20
H;ip<0.20
Ов. Н рж0.20
OC. Ho p=0.80
Hip>0.80
O E. H p=0.80
Hyip<0.80
H;ip>0.20
O D. H: p=0.80
H: p20.80
OF. H: p=0.20
H: pz0.20
The test statistic is z= (Round to two decimal places as needed.)
The P-value is (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
