total marked whales 34
total whales counted 387
total marked whales counted 28
what is the best estiment for the population of whales
To estimate the population of whales, we can use the concept of marking and recapturing.
We know that the total marked whales counted are 28, and the total marked whales are 34.
Using the marking and recapturing method, we can estimate that the proportion of marked whales in the total population is equal to the proportion of marked whales in the sample counted.
So, the estimated population of whales can be calculated as follows:
Total population of whales = (Total whales counted * Total marked whales) / Marked whales counted
Total population of whales = (387 * 34) / 28
Total population of whales ≈ 469.71
Therefore, the best estimate for the population of whales is approximately 470.
24
375
24
Using the formula mentioned earlier:
Total population of whales = (Total whales counted * Total marked whales) / Marked whales counted
Total population of whales = (375 * 34) / 24
Total population of whales = 5250 / 24
Total population of whales ≈ 218.75
Therefore, the best estimate for the population of whales is approximately 219.
wrong
Apologies for the incorrect calculation. Let's recalculate.
Total population of whales = (Total whales counted * Total marked whales) / Marked whales counted
Total population of whales = (375 * 34) / 24
Total population of whales ≈ 531.25
Therefore, the best estimate for the population of whales is approximately 531.

Using the formula mentioned earlier:
Total population of whales = (Total whales counted * Total marked whales) / Marked whales counted
Total population of whales = (191 * 14) / 8
Total population of whales = 26634 / 8
Total population of whales ≈ 3329.25
Therefore, the best estimate for the population of whales is approximately 3329.
wrong
Apologies for the mistake. Let's recalculate.
Total population of whales = (Total whales counted * Total marked whales) / Marked whales counted
Total population of whales = (191 * 14) / 8
Total population of whales ≈ 333.25
Therefore, the best estimate for the population of whales is approximately 333.
