![Carbon dioxide (Chapter 20]. Because plants use CO; to fuel photosynthesis, more CO; may cause trees and other
plants to grow faster. An elaborate apparatus allows researchers to pipe extra CO2 to a 30-meter circle of forest.
They selected two nearby circles in each of three parts of a pine forest and randomly chose one of each pair to
receive extra CO,. The response variable is the mean increase in base area in m² for 30 to 40 trees in a circle
during a growing season. We measure this in percent increase per year. The following are one year's data. This
is a matched pairs design. Compute and report differences to 10.001 in the single column table at the lower right.
Use a = 5%.
