## anonymous one year ago The table below shows the data for a random sample of fish that were collected from and later released into a lake: How many catfish are estimated to be present if a sample of 800 fish is collected from the lake? 208 260 348 372

Add the numbers of Catfish, Grass carp and Bluegill that were in the sample. Call that total number n. Then the probability of a Catfish in a very large sample of fish is 52/n. Therefore to estimate the number of Catfish in a sample of 800 we need to calculate $\large \frac{52}{n} \times \frac{800}{1}=you\ can\ calculate.$

@kropot72 i dont understand

The total number of fish in the first sample is 52 + 61 + 87 = 200 Therefore to estimate the number of Catfish in a sample of 800 we need to calculate $\large \frac{52}{200} \times \frac{800}{1}=?$

Yes, 208 Catfish is correct.
