•This paper presents a numerical method for the coverage interval determination.•The coverage interval is derived from distribution function.•The evaluation of mixed distribution is done by using the combined method.•This method is consisted of the MC method and the modified least-squares method.•The method presented in the paper is in a good agreement with the GUM method. This paper presents a numerical method for the coverage interval determination of the output variable while knowing the probability density functions of two non-dependent input variables. The coverage interval is derived from distribution function. In order to obtain the probability density function of the output variable, which is of mixed distribution type, the numerical combined method is applied, consisted of the Monte Carlo method and the modified least-squares method. The proposed method is applied for the symmetric distributions in the conducted emission measurements. The validation of the combined method showed its satisfactory level of accuracy.
