Answer:
D
Step-by-step explanation:
Answer:
The coronary heart disease specific mortality rate/density of participants in this cohort
= 13.57%
Step-by-step explanation:
a) Data and Calculations:
Total participants in the cohort = 7,000 persons
Total person-years contributed = 56,232
Death during follow-up = 1,890
Number of death due to coronary heart disease = 950
Mortality rate/density of participants in this cohort
= 950/7,000 * 100 = 13.57%
b) The result suggests that 13.57% of the 7,000 participants died during follow-up out of coronary heart disease. This number represents about 50% (950/1,890 * 100) of all deaths recorded during follow-up.
x-4>15.5
x>15.5+4
x>19.5
i suppose the answer is D since it is the closest to ^.
17000
17 * 100
17 tens
there in the order u put question in
