... we know that 95% of Normally distributed values are within two standard deviations of the mean. So we should not be surprised if 95% of various polls gave results that were near the mean but varied above and below that by no more than two standard deviations. This is what we mean by sampling error. ...

... where z(1 − α/2) is the (1 − α/2)-quantile of standard normal distribution. It was proved by several simulation studies, that the variance of the twoˆ is underestimated by Φ̂, and as such, the stage (or plug-in) estimator µ̂ interval estimate based on (7) leads to too narrow confidence intervals for ...
