1. The data in Table 7–6 were collected in a clinical trial to evaluate a new compound designed to improve wound healing in trauma patients. The new compound was compared against a placebo. After treatment for 5 days with the new compound or placebo, the extent of wound healing was measured. Is there a difference in the extent of wound healing between the treatments? (Hint: Are treatment and the percent wound healing independent?) Run the appropriate test at a 5% level of significance.
Use the data in Problem 1. Pool the data across the treatments into one sample of size n = 250. Use the pooled data to test whether the distribution of the percent wound healing is approximately normal. Specifically, use the following distribution 30%, 40%, 20%, and 10% and a = 0.05 to run the appropriate test.

(See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas numbered 17—32. The biologist chooses 16 plots at random and applies organic fertilizer. The other plots receive non-organic fertilizer. At the end of the study period, the percentage increase in the number of this plant is measured in each plot and compared for each type of fertilizer. Is this an experiment?
