About half had surgery; the rest were monitored. *After 12 years, nearly 6 percent of men who had immediate surgery died of cancer, compared with slightly more than 8 percent of those patients who were observed, which was not a great enough difference to reach statistical significance:" (R322) (a) About how many men were in each category? (b) About how many deaths were there in each category? (c) Construct the contingency table for this study.
