Determine if a Poisson experiment is described: Industrial injuries occur at a p

Question

Determine if a Poisson experiment is described:

Industrial injuries occur at a particular factory with a mean of 0.2 per week. Management knows that for various reasons (such as worn-out equipment) these injuries tend to occur within relatively short time periods of each other. They would like to find the probability that no industrial injuries occur tomorrow.

A.) not a Poisson experiment because the mean number of successful outcomes that occur in an interval is not constant or is not known

b.) Poisson experiment

c) not a Poisson experiment because the number of successes that occur in any two disjoint intervals are dependent

d.) not a Poisson experiment because the size of the interval in which the observations are made is not fixed

Explanation / Answer

Since it is given that these injuries tend to occur within relatively short time periods of each other, this will not be a Poisson distribution because:

The number of successes that occur in any two disjoint intervals are dependent

Option C is correct.
