Game wardens use experiments to help determine the number of squirrels in a specific area. Suppose 150 squirrels are caught, tagged, and released back into the wild. Six weeks later, 300 squirrels are caught with 12 found to have tags. Using this information, estimate the number of squirrels in the area.
A. 375
B. 500
C. 3,750
D. 5,000
A. 375
B. 500
C. 3,750
D. 5,000
We can use the proportion method to estimate the number of squirrels in the area:
Number of tagged squirrels in first sample / Total number of squirrels in first sample = Number of tagged squirrels in second sample / Total number of squirrels in the area
Plugging in the values we get:
150 / n = 12 / 300
Solving for n:
n = 3750
Therefore, the estimated number of squirrels in the area is 3750.
The answer is option C.
Number of tagged squirrels in first sample / Total number of squirrels in first sample = Number of tagged squirrels in second sample / Total number of squirrels in the area
Plugging in the values we get:

Solving for n:
n = 3750
Therefore, the estimated number of squirrels in the area is 3750.
The answer is option C.
