Current Attempt in Progress The manufacturer of a popular soda drink claims that one-out-of-five (20%) bottles of soda have a special bottlecap with a message to obtain a free bottle of soda. A group of students who frequently consume this soda drink believes that the true proportion is less than 20%. Over several weeks, the students obtain 64 bottles of soda, of which 8 bottles had a special bottlecap. The students will test whether the data provide convincing evidence that the true proportion of bottles with a special bottlecap is less than 0.20. A significance level of a = 0.05 is used. It is assumed that the 64 bottles of soda is a random sample of all such soda bottles. Find the point estimate for p, the test statistic and p-value for this test. Assume all conditions for the test have been met. The point estimate for p is i The test statistic is z = i The p-value is i .
