7.9 PRACTICE PROBLEMS 1. 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 heal ing is measured and the data are shown in Table 7-6. Is there a difference in the extent of wound healing by TABLE 7-6 Data for Practice Problems 1 and 2 Treatment New compound (n=125) Placebo (w=125) Percent Wound Healing 0-25 % 26-50% 51-75 % 76-100% 15 37 34 treatment? (Hint: Are treatment and the percent wound healing independent?) Run the appropriate test at a 5% level of significance. 41 10
