Auto Insurance: Interpret Graphs Consumer Reports rated automobile insurance companies and listed annual premiums for top-rated companies in several states. Figure 3-9 shows box-and-whisker plots for annual premiums for urban customers (married couple with one 17-year-old son) in three states. The box-and-whisker plots in Figure 3-9 were all drawn using the same scale on a TI-84Plus/TI-83Plus/TI-nspire calculator.

(a) Which state has the lowest premium? the highest?

(b) Which state has the highest median premium?

(c) Which state has the smallest range of premiums? the smallest interquartile range?

(d) Figure 3-10 gives the fi ve-number summaries generated on the TI-84Plus/
TI-83Plus/TI-nspire calculators for the box-and-whisker plots of Figure 3-9.
Match the fi ve-number summaries to the appropriate box-and-whisker plots.
