Poisson Distribution
This is often known as the distribution of rare events. Firstly, a Poisson process is
where DISCRETE events occur in a CONTINUOUS, but finite interval of time or
space. The following conditions must apply:
> For a small interval the probability of the event occurring is proportional to the size
of the interval.
>The probability of more than one occurrence in the small interval is negligible (i.e.
they are rare events). Events must not occur simultaneously
> Each occurrence must be independent of others and must be at random.
> The events are often defects, accidents or unusual natural happenings, such as
earthquakes, where in theory there is no upper limit on the number of events. The interval is on some continuous measurements such as lenght time or area.

The Moon’s orbit is not circular, and its distance from the Earth varies. One day, when the Moon is at closest approach, 25 diﬀerent astronomers each take one measurement of the Earth-Moon distance. The mean of these measurements comes out to be 363,105 kilometers, and their SD is 10 km. For each of the following four statements about this data, either state that it is true (in which case you need do nothing further) or false (in which case, explain...
