4. 1-/12 Points DETAILS DEVORESTAT9 14.2.017. MY NOTES ASK YOUR TEACHER In a genetics experiment, investigators looked at 295 chromosomes of a particular type and counted the number of sister chromatid exchanges on each. A Poisson model was hypothesized for the distribution of the numbers of exchanges 4 X Number of Exchanges 0 1 2 3 5 6 2 8 9 Observed Counts 5 25 41 sa 61 40 16 5 Test the fit of a Poisson distribution to the data by first estimating and then combining the counts for x and x 9 into one cell (Round your answers to one decimur place.)
