"The seedlings of understory trees in mature tropical forests must survive and grow under intermittent flecks of sunlight. How does the length of exposure to these flecks of sunlight (fleck duration) affect growth? "Leakey et al. (2005) experimentally irradiated seedlings of the Southeast Asian rainforest tree Shorea leprosula with flecks of light of varying duration while maintaining the same total irradiance to all the seedlings." This is a quoted question from our textbook. The data for 21 seedlings are listed in the associated file called Data 3 Sun flecks and growth.xlsx. Test the null hypothesis that fleck duration does not affect seedling growth. To do this, you will need to assess whether these data meet the requirements for parametric tests. Graphs and tests used to determine the correct test would be worth 2 marks. The relevant table(s) for the correct test would be worth 3 marks and a concluding statement would be worth2 marks. Finally, a box-plot illustrating your data, with all axes properly labeled, font sizes are large enough to read (such that your graph is as you would want it for publication) would be worth 4 marks.
