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 = 6
Mean number of catfish = 5.7
If the number of fish = 200
So, 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.
