The table shows the data of a random sample of fish that were collected from and later released into a lake.

Type of Fish Bass Eel Gar
Number of Fish 92 56 52

How many eels are estimated to be present if a sample of 1,000 fish is collected from the lake? 112

280

320

380

1 answer

To estimate the number of eels in the lake, we can use the proportion of eels in the sample compared to the total sample size.

In the sample, there were 56 eels out of a total of 92 + 56 + 52 = 200 fish.

So the proportion of eels in the sample is 56/200 = 0.28

If we collect a sample of 1,000 fish from the lake, we can estimate the number of eels in the lake by multiplying the proportion of eels in the sample by the total sample size:

0.28 * 1,000 = 280

Therefore, an estimated 280 eels would be present in the lake if a sample of 1,000 fish is collected.

So the answer is 280 eels.
