In one of the first studies of the Poisson distribution, von
Bortkiewicz[Notes 1] 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.
| 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.
