This reference document contains tables of confidence limits for proportions for all sample size from 1 through 100. For sample sizes 105 through 200, tables are provided at intervals of five. Tables are also provided for sample sizes of 500 and 1000. When a sample size is not included in one of the tables, a method is provided for interpolating between tabled values to obtain accurate confidence limits for any sample size less than 1000. Confidence limits have been computed for the most frequently used confidence levels i.g., 90, 95, and 99 percent. Data are complied into three tables. One consists of two-sided confidence limits, one consists of one-sided lower confidence limits, and the third consists of one-sided upper confidence limits. The confidence limits are given to three decimal places for samples of size 195 and less. Samples of size 200, 500, and 1000 are given to four decimal places to improve the accuracy of interpolations.
