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. O A. H p=0.80 H p#0.80 Oc. H p=0.20 H p 0.20 O B. H p=0.20 H. p<0.20 OD. H p= 0.80 H p> 0.80 O E. Ho p= 0.20 Hr p>0.20 OF.

Transcribed Image Text:Trials in an exxperiment 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 pollygraph 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 orignal.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.
DA. H p=0.80
Hp 0.80
OB. H p=0,20
H, p<0.20
OC. H p-0.20
HF p 0.20
O D. H, p= 0.80
H: p> 0.80
O E. Ho p-0 20
H p>0.20
OF. H p=D0.80
H p<0.80
The test statistic is 2=
(Round to two decimal places as needed.)
The P-value is
(Round to four decimal places as needed.)
