8. It proposed to fit the Poisson distribution to the following dat: (a) Compute the corresponding x^2 goodness of fit statistic. Hint In computing the sample mean treat 3

Solution

Find mean and std deviation for the data

p value =1

As p >0.05, the difference is not significant.

The data support the Poisson Model.
