Source: NIST/SEMATECH e-Handbook of Statistical Methods,. Another advantage is that the lower limit cannot be negative. One advantage of this procedure is that its worth does not strongly depend upon the value of n and/or p, and indeed was recommended by Agresti and Coull for virtually all combinations of n and p.

In addition the Agresti-Coull approach is used to compute better intervals. This computation assumes that the number of successes and sample measurements is large enough (normal approximation is used). This free online software (calculator) computes the critical values for one- and two-sided hypothesis tests about the population proportion. The only thing that is asked in return is to cite this software when results are used in publications. The non-commercial (academic) use of this software is free of charge.
