histogram: cross markers (black color), numerical simulation; circle markers (red color), analytical solution. The PDFs of and are both uniform distributions. and are 948 and 1052, respectively. The null hypothesis is the PDF of the simulated data with mean and variance given by (3) and (4), respectively. The means and standard deviations of and are ; ; ; . The sample number is 10000 and the number of bins is 60. The chi squared test is accepted at the significance level of 0.05. ; ; .
