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 ; ; ; . In this case, the sample number is 100000 and the number of bins is 1000. The chi squared test is accepted at the significance level of 0.05. ; ; .
