Based on the information displayed in the boxplots above, which of the following statements is true? Section 1 has the smallest interquartile range. The lowest score in section 2 is higher than the highest score in either of the other sections. Section 2 has the smallest range of scores. The top 25% of scores in section 2 are lower than the highest score in section 3.

In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315.
