Obtain a sample size that will ensure a margin of error of at most the one specified.

Margin of error=0.02

Confidence level=90%

Bank Breakup. In a nationwide survey, conducted by Pulse Opinion Research, LLC for Rasmussen Reports, a sample of American adults were asked whether they favor a plan to break up the 12megabanks, which currently control about 69%of the banking industry; 50%of those sampled responded in the affirmative. According to the report, "the margin of sampling error is 卤3percentage points with a 95%level of confidence." Find and interpret a 95%confidence interval for the percentage of all American adults who favor a plan to break up the 12megabanks.

In this Exercise, we have given the number of successes and the sample size for a simple random sample from a population. In each case,

a. use the one-proportion plus-four z-interval procedure to find the required confidence interval.

b. compare your result with the corresponding confidence interval found in Exercises 11.25-11.30, if finding such a confidence interval was appropriate.

x=16,n=20,90%level

a. Determine the sample proportion.

b. Decide whether using the one-proportion z-test is appropriate.

c. If appropriate, use the one-proportion z-test to perform the specified hypothesis test.

Factory Farming Funk. During one year, the U.S. Environmental Protection Agency reported that concentrated animal feeding

operations (CAFOs) dump 2 trillion pounds of waste into the environment annually, contaminating the ground water in 17 states and polluting more than 35,000 miles of our nation's rivers. In a survey of 1000 registered voters by Snell, Perry and Associates, 80% favored the creation of standards to limit such pollution and, in general, viewed CAFOs unfavorably. Find and interpret a 99% confidence interval for the percentage of all registered voters who favor the creation of standards on CAFO pollution and, in general, view CAFOs.
