I'm so confused with this lesson. I just did the work for question 3 on Connexus 5.6.6 (Estimating Population Size Quiz) and I got 6,600. that's not an answer.
Here's my work:
A fish and game warden captures and tags 66 deer and releases them. A month later, he captures 100 deer and finds that 17 of them have tags.
Total number of tagged deer in sample/total number of deer in sample = 17/100
Total number of tagged deer in population/total number of deer in population = 66/x
17/100 = 66/x
17x = 100*66=6600
I guess you could divide 17 into 6600. That would give you 388.235294, which if rounded to the nearest whole number is 389.
