Below is data from a Poisson distribution truncated at 0, that is all the observations that were equal to 0 where lost:
| x | Freq |
|---|---|
| 1 | 24 |
| 2 | 34 |
| 3 | 16 |
| 4 | 4 |
| 5 | 3 |
| 6 | 2 |
| 7 | 1 |
Find a 90% confidence interval for the Poisson rate \(\lambda\). Give some argument why your solution works.
