Answer 1

3. Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places.

90% confidence; n = 480, x = 120

0.0325
0.0406
0.0348
0.0387

Answer 2

5. Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p.

A survey of 865 voters in one state reveals that 408 favor approval of an issue before the legislature. Construct the 95% confidence interval for the true proportion of all voters in the state who favor approval.

0.438 < p < 0.505
0.444 < p < 0.500
0.471 < p < 0.472
0.435 < p < 0.508
