BONUS QUESTION Question 7. Tree diameter distributions from two forest ecosites - B049 and B127 were generated using R. Base on the R outputs below, test the hypothesis (Null hypothesis Ho: data are normally distributed, against alternate hypothesis; Ha: data are not normally distributed for each ecosite group). What do you conclude? Why do you come to this conclusion? (2 marks) Variables 8049 Ecosite B127 Ecosite His for Eco His for Ec 2,000- Histograms 1,500- lenc 3- Iency Mean 11.77 11.97 Std.
