Trials in an experiment with a polygraph include 98 results that include 22 cases of wrong results and 76 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.
O A. Ho p= 0.20
H p#0.20
O C. Ho p=0.80
H, p#0.80
O B. H, p= 0.80
H, p> 0.80
O D. H, p= 0.20
H, p> 0.20
O E. H, p=0.80
H, p<0 80
OF. H, p= 0.20
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 Ho. There
7 sufficient evidence to support the claim that the polygraph results are correct less than 80% of the time.
