There are many statistical methods to determine the correct probability distribution and one of them is Chi-Square Goodness of Fit Test. This statistical test can be also used to find out a probability distribution of time intervals between arrivals of customers at post office. Intervals between arrivals of customers occur in continuous time and therefore we consider continuous probable distributions.enhttp://creativecommons.org/licenses/by/4.0/probability distributioncustomer inputChi-Square Goodness of Fit TestArticlehttps://doi.org/10.26552/tac.C.2017.2.2
