Data are 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 in Table 7..6. Is there a difference in the extent of wound healing by treatment? (Hint: Are treatment and the percentage of wound healing independent?) Run the appropriate test at a 5% level of significance.
