Using a proportion, we can estimate the population:
340 tagged trout / x total population = 30 tagged trout / 600 captured trout
Solving for x, we get:
x = (340 * 600) / 30 = 6800
Therefore, the best estimate for the trout population is D) 6,800.
A group of researchers wanted to monitor the trout population, so they marked 340 trout with tags. Later, they captured 600 trout and found that 30 of them had tags. What is the BEST estimate for the trout population?
A 6,200
B 6,600
C 6,400
