A. The distribution of fatal work injuries in the west is 43% transportation, 19% equipment,
14% assaults, 13% falls, 9% harmful fumes, and 2% fires.
B. The distribution of fatal work injuries in the west is 2895 transportation, 1161
equipment, 802 assaults, 754 falls, 535 harmful fumes, and 84 fires.
C. The distribution of fatal work injuries in the west differs from the expected distribution.
What is the alternate hypothesis, H?
A. The distribution of fatal work injuries in the west is the same as the expected
distribution.
VB. The distribution of fatal work injuries in the west differs from the expected distribution.
C. The distribution of fatal work injuries in the west is 43% transportation, 19% equipment,
