Concept explainers
To explain : which sample will give a more accurate estimation of average weight of snapping turtles.
Answer to Problem 15E
The sampling method used by the second scientist is likely to give better result.
Explanation of Solution
Given information :
The first scientist weights all of the snapping turtles that live in a certain ponds.
The second scientist weighs a number of snapping turtles from several ponds.
The sampling method used by the second scientist is likely to give better result because it takes more than one ponds as a sample into his account to determine the average weight of snapping turtles thus it make this method of sampling representative.
