Question

Using six random samples, the average number of catfish in the samples was 5.7. If the total population of fish in the pond is 200, the proportion of catfish in the pond will be 5.7 20 = x 200 . What is the predicted number of catfish in the pond?

Answer 2

The predicted number of catfish in the pond is 57.

Explanation:

We are given that the average number of catfish in the samples was 5.7. If the total population of fish in the pond is 200, the proportion of catfish in the pond will be 5.7/20 = x/200.

We have to calculate the predicted number of catfish in the pond.

The given proportion to us is;

`(5.7)/(20)=(x)/(200)`

Cross multiplying both the fractions we get;

`5.7 * 200=x * 20`

`(57)/(10) * 200=x * 20`

`{57} * 20=x * 20`

`x = (57 * 20)/(20)`

`x = 57`

So, the predicted number of catfish in the pond is 57.
