16. For a class project, a political science student at a large university wants to determine the percent of students that are registered voters. He surveys 500 students and finds that 300 are registered voters. Compute a 90% confidence interval for the true percent of students that are registered voters and interpret the confidence interval.

Step 1
We are given a sample size (n) of 500 students, and 300 of them are registered voters. So, the sample proportion (p̂) is 300/500 = 0.6. Show more…

In a survey taken among college students, 300 of 500 students belonging to past semesters favored certain proposition, while 64 of 100 belonging to the first semesters were in favor of the proposition. Find a 99% confidence interval for estimating the true difference between the proportions of seniors and first semesters who favor the proposition. If the estimation error found in part a is to be halved. What should the sample size be? Use a 95% confidence level.

In a random sample of 400 registered voters, 120 indicated they plan to vote for candidate A. Determine a confidence interval for the proportion of all the registered voters who will vote for Candidate A. a. Calculate the standard error of this problem b. Calculate the margin of error c. Find 90% confidence interval d. With a .95 probability, how large of a sample needs to be taken to provide a margin of error of .08 or less
