From the MAA

Precision of the annual estimate of operations is measured by the sampling error or 95% confidence interval. The confidence interval is an estimated range (plus and minus the annual operations) with whichone can be 95% confident of the true range of operations. The sampling error is simply the confidence interval expressed in percentage. The annual analysis form identifies the annual operations as well as the sampling error and the 95% confidence interval.
