2. The following data was collected in a clinical trial evaluating a new compound designed to improve wound healing in trauma patients. The new compound is compared against a placebo. After treatment for 5 days with the new compound or placebo the extent of wound healing is measured and the data are shown below. Percent Wound Healing 51-75% Treatment 0-25% 26-50% 76-100% New Compound (n=125) Placebo (n=125) 15 37 32 41 36 45 34 10 Is there a difference in the extent of wound healing by treatment? (Hint: Are treatment and the percent wound healing independent?) P-value < 0.005 at a 5% level of significance.
