Trials in an experiment with a polygraph include 98 results that include 23 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. Ho p=0.80
H₁: p>0.80
OC. Ho p=0.20
H₁: p 0.20
O E. Ho p=0.20
H₁: p<0.20
B. Ho: p=0.80
H₁: p<0.80
OD. Ho: p=0.20
H₁: p > 0.20
OF. Ho: p=0.80
H₁: p 0.80
The test statistic is z =
