A random sample of 4000 citizens yielded 2250 who are in favor of gun control legislation. Estimate the true proportion of all Americans who are in favor of gun control legislation using a 90% confidence interval. Express the answer in the form ± E and round to the nearest ten-thousandth.

ME =
z = 1.645 and p = 2250/4000 = .5625
ME = round to the nearest ten-thousandth.
2250 ± ME
|
= CI z = value
90% z =1.645
92% z = 1.751
95% z = 1.96
98% z = 2.326
99% z = 2.576
