Can you please help me answer this question?

1. The following data was collected in a clinical trial evaluating 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 and the data are shown below. (10 points) Percent Wound Healing Treatment 0-25% 26-50% 51-75% 76-100% New Compound (n=125) 15 37 32 41 Placebo (n=125) 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?) Run the appropriate test at a 5% level of significance
