To gather information about the elk population, biologist marked 75 elk. Later, they flew over the region and counted 250 elk, of which 15 were marked. What is the best estimate for the elk population?

Answer 1

One way to approach this problem is to use a proportion:

(markeds in sample) / (total in sample) = (markeds in population) / (total population)

We can plug in the numbers we know:

15 / 250 = 75 / x

where x is the total elk population. We can cross-multiply and solve for x:

15x = 75 * 250
x = 18,750

Therefore, the best estimate for the elk population is 18,750.

Answer 2

A 1,250
B 1,300
C 1,200
D 1,350
these the only options they have..
