Sampling Problems. Sampling techniques can be used to estimate physical quantities. To estimate a large quantity, you might measure a representative small sample and find the total quantity by “scaling up.” To estimate a small quantity, you might measure several of the small quantities together and “scale down.” In each of the following, describe your estimation technique and answer the questions.
Example: How thick is a sheet of a paper?
Solution: One way to estimate the thickness of a sheet of paper is to measure the thickness of a ream (500 sheets) of paper. A particular ream was 7.5 centimeters thick. Thus, a sheet of paper from this ream was 7.5 cm / 500 = 0.015 cm, or 0.15 millimeter, thick.
72. How much does a sheet of paper weigh?
