The article €œA Nation Ablaze with Change€ ( USA Today, July 3, 2001) gave the following data on percent-age increase in population between 1990 and 2000 for the 50 U. S. states. Each state is classified as belonging to the eastern or western part of the United States ( the states are listed in order of population size):

a. Construct a stem- and- leaf display for the entire data set. Regard the observations as having two digits to the left of the decimal place. For example, consider 8.5 as 08.5. Also truncate leaves to a single digit. For example, a leaf of 8.5 would be truncated to 8.
b. Comment on any interesting features of the display. Do any of the observations appear to be outliers?
c. Now construct a comparative stem- and- leaf display for the eastern and western states. Write a few sentences comparing the two distributions.
