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 injuries occurring in that region. At a = 0.05 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. U "a b.
