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


Type of Fish Catfish Grass Carp Bluegill
Number of Fish 52 61 87


How many grass carps are estimated to be present if a sample of 800 fish is collected from the lake?
122
148
244
348
Question

Answer 1

Use the data in the table to calculate (number of grass carps) / (total # of fish). That’ll give you the proportion of grass fish out of all fish. From there, multiply that by 800 fish to get the # of grass carp per 800 fish sample.
