Question

Trials in an experiment with a polygraph include 96 results that include 23 cases of wrong results and 73 cases of correct results. Use a 0.01 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.

Answer #1

Trials in an experiment with a polygraph include 96 results that
include 23 cases of wrong results and 73 cases of correct results.
Use a 0.01 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...
