Best ResponseYou've already chosen the best response.1Add 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 \[\large \frac{52}{n} \times \frac{800}{1}=you\ can\ calculate.\]

Best ResponseYou've already chosen the best response.1The 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 \[\large \frac{52}{200} \times \frac{800}{1}=?\]
