Answer #1

Answer: True

Explanation : Five year survival rate: It gives the number of people still alive after 5 years with a specific disease.

Rate: It gives the amount of events occurring in a specific period of time.

Proportion : It also gives the amount of events occurring in a specific period of time but it mentions the total amount.

Example: The five year survival rate for lung cancer in India is 60%.

Here as a rate it gives that in a five year period of time there are 60% people are alive with lung cancer (It is diagnosed before five years).

As a proportion , it mentions from the total amount that is out of 100, 60 people are alive with lung cancer(it is diagnosed before five years).

So it is a rate but its too a proportion.
