Interpolation methods are used to estimate heights above sea level for locations where direct measurements are unavailable. In an article in the Journal of Survey Engineering, a weightedaverage method of interpolation for estimating heights from GPS measurements is evaluated. The method made large errors (errors whose magnitude was above a commonly accepted threshold) at 26 of the 74 sample test locations. Find a 90% confidence interval for the proportion of locations at which this method will make large errors.
