Answer 2

Answer: There would be 190 catfish in all 200 samples in the population.

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,

`(6)/(5.7)=(200)/(x)\\\\6x=5.7* 200\\\\6x=1140\\\\x=(1140)/(6)\\\\x=190`

Hence, there would be 190 catfish in all 200 samples in the population.
