$3\mathrm{.}1$ please help and assist me in learning how to solve this.

Let $P()$ be the Poisson distribution with parameter $($review the textbook or Wikipedia for the

Poisson distribution if necessary$).$ Use the built$-$in $R$ command rpois to generate ${10}^3$ samples

from the Poisson distribution with parameter $=4.$ Plot the empirical cdf on the sample plot

as the actual cdf$.$ Remember to submit the code that does this and print out the resulting figure.
