Trials in an experiment with a polygraph include 97 results that include 22 cases of wrong results and 75 cases of correct results. Use a 0.01 significance level to t 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 ab 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 binomia distribution. Let p be the population proportion of correct polygraph results. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: p=0.80 H,: p>0.80 B. Ho: p= 0.80 H,:p<0.80 O C. Ho: p=0.20 H,: p#0.20 O D. Ho: p=0.20 H,: p<0.20 O E. Ho: p=0.80 OF.

3 - A water manufacturer claims that its product is 330 ML. The amount of water has a normal distribution. Quality manager takes 25 products every hour and calculate the amount of the water. The mean amount of water at 10:00 yields the average amount of 315 ML and variance of 9 ML. Test the claim that amount of the water in the bottles is at least 330 ML. Use significance level as 0.05. What is the hypothesis? What is the test statistics? If both of the answers are correct you got the points, otherwise you lose all points.
