Answer: Option C
Step-by-step explanation:
In group(1), the risk is= 5/2000 x 100
= 0.25
In group(2), the risk is= 5/1000 x 100
= 0.5
The sample relative risk is= 0.25/0.5
= 0.5
So, option C is correct.
The answer is 110 because if you multiply 8•16=128 and 18 cars are used, you subtract 128-18 which is 110.
