What is the death rate if there are 800 individuals alive at the beginning of the 1 to 2-year age interval and 200 individuals die during this interval?

0.25

The correct answer is Option (4)- 0.25

The death rate can be calculated by dividing the number of individuals who died during a specific time interval by the total number of individuals alive at the beginning of that interval.

In this case, 200 individuals died during the 1 to 2-year age interval, and there were 800 individuals alive at the beginning of this interval. Therefore, the death rate can be calculated as:

Death rate = (Number of deaths / Number of individuals alive) * 100 = (200 / 800) * 100 = 25

So, the death rate is 25%. Therefore, the correct option is (4) 0.25, as it represents the death rate in decimal form.
