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 .10 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.

For one binomial experiment, n1 = 75 binomial trials produced r1 = 45 successes. For a second independent binomial experiment, n2 = 100 binomial trials produced r2 = 65 successes. At the 5% level of significance, test the claim that the probabilities of success for the two binomial experiments differ. (a) Compute the pooled probability of success for the two experiments. (Round your answer to three decimal places.) (b) Compute p̂1 - p̂2. p̂1 - p̂2 = (c) Compute the...
