Problem 9. Suppose we wish to compare two treatments for breast cancer, viz., simple master- tomy (S) and radical mastectomy (R). We form matched pairs of women who are within the same decade of age and with the same clinical condition to receive the two treatments and measure their 5-year survival. The results are given (L-lived at least 5 years, D-died within 5 years) below. Perform an analysis of this data, and interpret your results.
