The figure above summarizes the heights, in centimeters, of approximately 400 pine seedlings six years after they were planted at a center for environmental study. Approximately half of the trees were fertilized yearly, and the remaining trees were never fertilized. Which of the following statements about the medians and interquartile ranges (IQRS) of the heights of the two groups of trees 6 years after being planted is true? (A) The medians and IQRS are the same for the unfertilized trees and the fertilized trees. (B) The median for the unfertilized trees is greater than the median for the fertilized trees, and the 1QR is also greater for the unfertilized trees. (C) The median for the unfertilized trees is the same as the median for the fertilized trees, and the IQR is greater for the unfertilized trees. (D) The median for the unfertilized trees is less than the median for the fertilized trees, and the IQR is greater for the unfertilized trees. (E) The median for the unfertilized trees is less than the median for the fertilized trees, and the IQR is less for the unfertilized trees.
