|
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 occurrences of every third arrival is also exponential.
|
|
|
Both (A) and (C).

Question 14 Explanation:
In Poisson distribution, the mean is not equal to the twice the variance.
Option C is also False, because waiting time is dependent on the service discipline.
Option C is also False, because waiting time is dependent on the service discipline.
