Concept explainers
(a)
To compute an estimate of the total number of fish in the lake.
(a)
Answer to Problem 5.6E
There are approximately 150 fish.
Explanation of Solution
We will calculate this by using the equation of capture-recapture method:
Where
Thus, we have,
There are approximately 150 fish.
(b)
To identify that is the number of fish you calculated in part (a) is definitely, probably, probably not, or definitely not equal to the actual number of fish in the lake and explain.
(b)
Answer to Problem 5.6E
Probably not equal to.
Explanation of Solution
The number of fish you calculated in part (a) is probably notequal to the actual number of fish in the lake. This was an estimate, so it is very unlikely that it could predict the exact number of fish in the pond.
(c)
To explain why the capture-recapture sampling method used in this activity is not biased.
(c)
Explanation of Solution
The capture-recapture sampling method used in this activity is not biased because the method in which fish are selected can be assumed to be completely random.
