Answer 2

Answer:  The correct answer is 1,500

Explanation:

The available answers to this question are:

225

1500

3750

4500

Average the recorded trout:

Avg = (88 + 80 + 57) / 3 = 75

Sample size = 50 acres

Lake size = 1,000 acres

Number of samples = 1000 / 50 = 20

Use the average for population:

75 * 20 = 1,500
