Textbook Question
Chapter 2.2, Problem 16E
The article “Bicyclists and Other Cyclists” (Annals of Emergency Medicine [2010]: 426) reported that in 2008, there were 716 bicyclists killed on public roadways in the United States, and that the average age of the cyclists killed was 41 years. These figures were based on an analysis of the records of all traffic-related deaths of bicyclists on U.S. public roadways (this information is kept by the National Highway Traffic Safety Administration).
- a. Does the group of 716 bicycle fatalities represent a census or a sample of the 2008 bicycle fatalities?
- b. If the population of interest is 2008 bicycle traffic fatalities, is the given average age of 41 years a number that describes a sample or a number that describes the population?
