Below is a "back-to-back" stem-and-leaf display that shows two data sets at once€”one going to the left, one to the right The display compares the percent change in population for two regions of the United States (based on census figures for 2000 and 2010). The fastest growing state was Nevada at 35%. To show the distributions better, this display breaks each stem into two lines, putting leaves 0-4 on one stem and leaves 5-9 on the other.

a) Use the data displayed in the stem-and-leaf display to construct comparative boxplots.
b) Write a few sentences describing the difference in growth rates for the two regions of the United States.
