Home Took O Shee tom table, the cell references again are automatically updated 7.9 PRACTICE PROBLEMS (e-g., the formula in cell H12 is *=(D5-15)^2/15"). The y test statistic is computed by summing the (0 - 1. Data are collected in a clinical trial evaluating a new E) /E values in the twelve cells. The test statistic is placed in cell compound designed to improve wound healing in G14 and is computed using "- SUM (F9:H12)" The p-value is trauma patients. The new compound is compared against a placebo. After treatment for 5 days with the computed with the CHIDIST function using *= CHIDIST (G14, 6)* where 6 reflects the degrees of freedom (df = (r = 1) new compound or placebo, the extent of wound heal- ing is measured and the data are shown in Table 7-6. X (c - 1) = 3(2) = 6). The test statistic and p-value are shown Is there a difference in the extent of wound healing by in Figure 7-28. In this test, the test statistic is y' = 60.44 and the p-value is practically zero (3.66 X 10-11). We reject Ho because p = TABLE 7-6 Data for Practice Problems 1 and 2 0 Car - 0.05. We have statistically significant evidence at a -0.05 to show that He is false, or that living arrangement and exercise are not independent (i.e., they are dependent or Percent Wound Healing related).
