Definitions:

Poisson Distribution

A discrete probability distribution expressing the probability of a given number of events occurring in a fixed interval of time or space, assuming that these events occur with a known constant mean rate and independently of the time since the last event.

Arrival Rate

In the context of queueing theory, it refers to the average number of items (customers, calls, etc.) arriving at a service facility per unit of time.

Level of Significance

The threshold below which a p-value is considered to indicate a statistically significant result, typically set at 0.05 or 5%.

Degrees of Freedom

Represents the number of independent values or quantities which can be assigned to a statistical distribution without violating any constraining conditions.
