use the approximate confidence interval [ ˆp-√(ˆp(1−ˆp)/n, ˆp+z√(ˆp(1−ˆp)/n), as an interval estimate for p, where z is the appropriate quantile for the standard normal distribution
4.5.3.3
define the approximate margin of error E=z√(ˆp (1−ˆp)/n and understand the trade-off between margin of error and level of confidence
4.5.3.4
use simulation to illustrate variations in confidence intervals between samples and to show that most but not all confidence intervals contain p
