Expert Solution

Step 1

Given
The total number of caribou tagged (population) $= 240$
The number of caribou caught this year (sample) $= 350$
The number of tagged among caribou caught this year (sample) $= 60$

Let the total number of caribou population size be X .

The proportion of caribou caught in sample be p $= \frac{60}{350}$

The proportion of caribou caught in population be $\hat{p} = \frac{240}{X}$
