In one of the first studies of the Poisson distribution, von Bortkiewicz considered the frequency of deaths from kicks in the Prussian army corps. From the study of 14 corps over a 20-year period, he obtained the data shown in Table.

Mule kicks.

Number of deaths	Number of corps with [math]x[/math] deaths in a given year
0	144
1	91
2	32
3	11
4	2

Fit a Poisson distribution to this data and see if you think that the Poisson distribution is appropriate.
