(a) Fit a Poisson distribution to the above data, using the method of maximum likelihood. (b) Group the data by number of claims per day into four groups: 1 2 3 3 or more Apply the chi-square goodness-of-fit test to evaluate the null hypothesis that the claims follow a Poisson distribution. Determine the result of the chi-square test.
