Transcribed Image Text:
Trials in an experiment with a polygraph include 99 results that include 24 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 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
OA. H₂: D=0.20
H₁: p<0.20
OC. Hp-0.80
H, p 0.80
OE. Hp-0.80
H, p<0.80
The test statistic is z-(Round to two decimal places as needed.)
The P-value is (Round to four decimal places as needed.)
OB. H: p 0.20
H, p0.20
OD. Ho p=0.20
H. p>0.20
OF HD 0.80
H₁: p>0.80
Identify the conclusion about the null hypothesis and the final conclusion that addresses the original claim
H There
sufficient evidence to support the claim that the polygraph results are correct less than 80% of the time
