Question
Trials in an experiment with a polygraph include 96 results that include 22 cases of wrong results and 74 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,
altemative 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 a
an approximation of the binomial distribution.
Let p be the population proportion of correct polygraph results. Identify the null and altenative hypotheses. Choose the correct answer below.
O A. Hg: p=0.20
O B. H: p= 0.80
H,: p#0.20
H;: p40.80
OC. Ho: p=0.80
H,:p<0.80
O D. Ho: p=0.20
H,:p<0.20
OE. Ho p=0.80
OF. H p=0.20
H: p>0.80
H: p>0.20
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.
V Họ. There
V sufficient evidence to support the claim that the polygraph results are correct less than 80% of the time.
