Question 2
A news article appearing in a national paper stated that The fatality rate from use of firearms sank to a record low last year, the government estimated Friday.
But the overall number of violent fatalities increased slightly, leading the government to urge an increase in police forces in major urban areas. Overall, 15,600 people died from violent crimes in 2005, up from 15,562 in 2004, according to projections from a government source. Is the figure15,600 a descriptive statistic or an inferential statistic? Is the figure 15,562 a descriptive statistic or an inferential statistic?
A) The figure15,600 is a descriptive statistic since it reflects the actual number of deaths from violent crimes for the year 2004. The figure15,562 is an inferential statistic since it is indicated in the statement that it is a projection (probably based on incomplete data for the year 2005).
B) The figure15,600 is a descriptive statistic since it reflects the actual number of deaths from violent crimes for the year 2005. The figure15,562 is a descriptive statistic as well.
C) The figure15,600 is an inferential statistic since it is indicated in the statement that it is a projection (probably based on incomplete data for the year 2005). The figure 15,562 is a descriptive statistic since it reflects the actual number of deaths from violent crimes for the year 2004.
D) The figure15,600 is an inferential statistic since it is indicated in the statement that it is a projection (probably based on incomplete data for the year 2004). The figure15,562 is an inferential statistic as well.
