Point estimate = (76.1 + 90.5)/2 = 83.3. All confidence intervals are of the form “point estimate” plus/minus the “margin of error”. 0.071 + e = 0.113. The pollster will take the results of the sample and construct a 90 % confidence interval for the true proportion of all voters who support the candidate. Next, the error term e is the distance from p to the end of the interval.
