Question

If 8 individuals in a laboratory population of 80 fruit flies died in a week, then what would be the death rate for the population for the said period?

Answer 1

The death rate is calculated by dividing the number of individuals who died by the total population size during the given period.

Given:

The number of individuals who died = 8,

The total population size = 80,

Using the formula:

`"Death Rate" = "Number of deaths"/"Total population"`

`"Death Rate" = 8/80`

∴ Death Rate = 0.1

Thus, the death rate for the population during the said period is 0.1, meaning 10% of the population died that week.
