You are developing a simulation moel of a service system and are trying to create an input model of the customer arrival process. You have the following four observations of the process of interest: [86,24,9,50] an dyou are considering either an exponential distribution or a uniform distribution for the model. Using the data to estimate any necessary distribution parameters, develop Q-Q plots for both cases. Note that your graph doesn't have to be perfectly to scale, but it does have to be readable and you need to specifically compute the graph values.
I understand how to find the Quantiles by using (i-0.5)/n but how do I find the exponential Quartiles and Uniform Quartiles. From that data how do I estimate the parameters?
