Use α = 0.05 and k = 3 equal-probability intervals. 5. Records pertaining to the monthly number of job-related injuries at an underground coal mine were being studied by a federal agency. The values for the past 100 months were as follows: Injuries per Month Frequency of Occurrence 0 35 1 40 2 13 3 6 4 4 5 1 6 1 (a) Find the maximum likelihood estimator for the λ parameter of Poisson distribution. (b) Apply the chi-square test to these data to test the hypothesis that underlying distribution is Poisson. Use a level of significance α = 0.05. (c) Apply the chi-square test to these data to test the hypothesis that underlying distribution is Poisson with mean 1.0. Use a level of significance α = 0.05....
