Concerned about reports of discolored scales on fish caught downstream from a new chemical plant, scientists set up a field station in a shoreline public park. For one week, they asked fishermen there to bring any fish caught to the field station for a brief inspection. At the end of the week, the scientists found that 18% of the 234 fish submitted for inspection displayed the discoloration. A. If discolored fish are not equally likely to be caught as normal fish, or fisherman are more disposed to bring discolored fish than normal fish, then the sample will be biased and resulting estimation will be biased. B. If the population of fish is less than 10 times the samplesize, 234, then the sample will be too large and the resulting estimation will be inaccurate. C. If discolored fish are not equally likely to be caught as normal fish, or fisherman are more disposed to bring discolored fish than normal fish, then the sample will be representational and the resulting estimation will be unbiased. D. If the population of fish is less than 10 times the samplesize, 234, then the sample will be sufficiently large and the resulting estimation will be accurate.
