4. 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= 0.10 can you conclude that the distribution of fatal work injuries in the west is different from the national Transportation distribution? Complete parts a through d below. Cause National % Western Frequency 2890 1162 43% Equipment Assaults 19% 15% 803 13% 753 Falls Harmful fumes 7% 534 Fires 3% 89 a. State H, and H, and identify the claim. What is the null hypothesis, H,? O A. The distribution of fatal work injuries in the west is 2890 transportation, 1162 equipment, 803 assaults, 753 falls, 534 harmful fumes, and 89 fires. O B. The distribution of fatal work injuries in the west differs from the expected distribution. OC. The distribution of fatal work injuries in the west is 43% transportation, 19% equipment, 15% assaults, 13% falls, 7% harmful fumes, and 3% fires. What is the alternate hypothesis, H,? O A. The distribution of fatal work injuries in the west is the same as the expected distribution. O B. The distribution of fatal work injuries in the west differs from the expected distribution. OC. The distribution of fatal work injuries in the west is 43% transportation, 19% equipment, 15% assaults, 13% falls, 7% harmful fumes, and 3% fires. Which hypothesis is the claim? O Ho O H. b.
