- 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 occuring 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. Equipment Cause National % 44% Western Frequency Transportation 2895 18% 1160 Assaults Falls Harmful fumes 14% 803 13% 754 9% 532 Fires 2% 87 O B. The distribution of fatal work injuries in the west is the same as the expected distribution. O C.
