Question

In​ 2008, a highway safety administration reported that the number of pedestrian fatalities in City A was 65 and that the number in City B was 45. Can we conclude that pedestrians are safer in City​ B? Why or why​ not?

Answer 1

Answer: No.

Step-by-step explanation:

For those fatalities to be comparable, the data produced should provide the number of fatalities per pedestrian as well.

Statistical data used in research is part of a bigger picture denominated the​ population. If City B has fewer pedestrians, or City A has more, the explanation to that difference in fatalities has nothing to do with city B being safer, but with being less populated with pedestrians.
