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?

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,

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

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
