calculate the crude cause-specific mortality rate for cancer. Total midyear population, Old-town, 2015 = 8,000,000 All causes- 40000 Cancer- 6000 Unintentional injury- 1000 Alzheimer's Disease-500 Group of answer choices a)(40,000 / 8,000,000) * 100,000 = 500 per 100,000 b)(6,000 / 40,000) * 100,000 = 15,000 per 100,000 c)(6,000 / 8,000,000) * 100,000 = 75 per 100,000 d)(6,000 / 41,500) * 100,000 = 14,458 per 100,000
