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 0.05 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.
ОВ. Но: р3 0.20
H,: p+0.20
O A. Ho: p= 0.80
H,: p<0.80
OC. Ho: p= 0.20
H;: p<0.20
O D. Ho: p= 0.80
H;: p#0.80
O E. Ho: p= 0.80
H,: p>0.80
OF. Ho: 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 Hg. There
sufficient evidence to support the claim that the polygraph results are correct less than 80% of the time.
