The mean number of catfish in all 6 samples is approximately 5.7. If 200 fish are in the pond, which proportion can be used to predict the number of catfish in the population?

Answer: There would be 190 catfish in all 200 samples in the population.Step-by-step explanation:Since we have given that Number of fish = 6Mean number of catfish = 5.7If the number of fish = 200So, we need to find the proportion to find the number of catfish in the population.Let the number of catfish in the population be 'x'.According to question, it becomes,[tex]\dfrac{6}{5.7}=\dfrac{200}{x}\\\\6x=5.7\times 200\\\\6x=1140\\\\x=\dfrac{1140}{6}\\\\x=190[/tex]Hence, there would be 190 catfish in all 200 samples in the population.
