NW Violent Crimes Use the violent crime rate data from Problem 33 to answer each of the following:
- a. Round the data to the nearest ten (for example, round 603.2 as 600).
- b. Draw a stem-and-leaf plot, treating the hundreds position as the stem and the tens position as the leaf (so that 4|5 represents 450).
- c. Redraw the stem-and-leaf plot using split stems.
- d. In your opinion, which of these plots better summarizes the data? Why?
33. NW Violent Crimes Violent crimes include murder, forcible rape, robbery, and aggravated assault. The data on the following page represent the violent-crime rate (crimes per 100,000 population) by state plus the District of Columbia in 2013.
