Problem

Is the use of significant figures in each of the following statements appropriate?

On July 1, 2005, the population of Cook County, Illinois, was 5,303,683.

Solution

We’re being asked to determine if the use of significant figures in the following statement appropriate.


Recall that the significant figures in a measured quantity include one estimated digit, the last digit of the measurement. The significant figures indicate the extent of the uncertainty of the measurement


Certain rules must be followed so that a calculation involving measured quantities is reported with the appropriate number of significant figures.


Given: On July 1, 2005, the population of Cook County, Illinois, was 5,303,683.
