Medicine A Medicine B Medicine C Significant 56 82 60 Improvement Slight 44 18 40 Improvement (a) At a = 0.01, is there enough evidence to conclude that the treatment and result are independent? (b) Find the p-value for the test in (a) using Chi-square table. (c) From the sample data above, it seems that there is no difference in significant improvement on helping children with pain from musculoskeletal injuries using Medicine A or Medicine C. Conduct an appropriate test on it using 5% level of significance.
