5. Park Rangers wanted to estimate the total number of wild mustangs in Central Oregon. They tagged 30 wild mustangs and sent them back to the herd. They recorded the mustang population once a month for the next three months as shown below.

Month 1 Month 2 Month 3
tagged mustangs in sample 8 10 15
total mustangs in sample 100 150 200

c. The rangers combined the three months into one large sample so they could consider a sample of 100 + 150 + 200 = 450 mustangs. Estimate the size of the wild mustang population.
