Grasshoppers are distributed at random in a large field according to a Poisson process with parameter a 5 2 per square yard. How large should the radius R of a circular sampling region be taken so that the probability of finding at least one in the region equals 0.99?

Answers

In this question, the Poisson distribution is used.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

Parameter of 5.2 per square yard:

This means that [tex]\mu = 5.2r[/tex], in which r is the radius.

How large should the radius R of a circular sampling region be taken so that the probability of finding at least one in the region equals 0.99?

We want:

[tex]P(X \geq 1) = 1 - P(X = 0) = 0.99[/tex]

Thus:

[tex]P(X = 0) = 1 - 0.99 = 0.01[/tex]

We have that:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-5.2r}*(5.2r)^{0}}{(0)!} = e^{-5.2r}[/tex]

Then

[tex]e^{-5.2r} = 0.01[/tex]

[tex]\ln{e^{-5.2r}} = \ln{0.01}[/tex]

[tex]-5.2r = \ln{0.01}[/tex]

[tex]r = -\frac{\ln{0.01}}{5.2}[/tex]

[tex]r = 0.89[/tex]

Thus, the radius should be of at least 0.89.
