In a genetics experiment, investigators looked at 300 chromosomes of a particular type and counted the number of sister-chromatid exchanges n each. A Poisson model was hypothesized for the distribution of the number of exchanges. Test the fit of a Poisson distribution to the data.
Number of exchanges | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Observed Counts | 6 | 24 | 42 | 59 | 62 | 44 | 41 | 14 | 6 | 2 |
