28. The national distribution of fatal work injuries in a country is shown in the table to the right under National %. You believe that the distribution of fatal work injuries is different in the western part of the country and randomly select 6231 fatal work Transportation injuries occurring in that region. At a = 0.025 can you conclude that the distribution of fatal work injuries in the west is different from the national distribution? Complete parts a through d below. a.
