Answer the following:
Which of the following statements are FALSE?
- For poisson distribution, the mean is twice the variance.
- In queuing theory, if arrivals occur according to poisson distribution, then the inter-arrival time is exponentially distributed.
- The distribution of waiting time is independent of the service discipline used in selecting the waiting customers for service.
- If the time between successive arrivals is exponential, then the time between the occurences of every third arrival is also exponential.
