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.
