(4) Based on Table 3.2, what are the chi-square values for X1 and X2 (using Wald test), respectively? (5) Based on Table 3.2, obtain odds ratio for X1 and X2, respectively. Interpret odds ratios. (6) Write the equation to show 95% condent interval for odds ratio (OR) of X1. (6) Write the equatiOn to show 95% condent interval for odds ratio (OR) of X1.
