A waiting-line problem that cannot be modelled by standard distributions has been simulated.The table below shows the result of a Monte Carlo simulation.(Assume that the simulation began at 8:00 a.m.and there is only one server.
a.What is the average waiting time in line?
b.What is the average time in the system?
Definitions:
Least Squares Regression
A statistical method used to determine the line of best fit by minimizing the sum of squares of the residuals.
Residual
The difference between an observed value and the predicted value in a statistical model.
Observed Value
The actual value measured or recorded during an experiment or observation.
Residual Plot
Graphical representation of the residuals that can be used to determine whether the assumptions made about the regression model appear to be valid.
