Question

Patients with advanced terminal cancer of the stomach and breast were treated with ascorbate in an attempt to prolong survival [87]. Table 9.4 shows survival times (days). Work with the data on the log scale.

TABLE 9.4 Survival Times (Days) for Patients with Two Types of Terminal Cancer
Stomach: 25, 42, 45, 46, 51, 103, 124, 146, 340, 396, 412, 876, 1112

Breast: 24, 40, 719, 727, 791, 1166, 1235, 1581, 1804, 3460, 3808

a. Use the bootstrap t method and bootstrap variance estimate to construct 95% confidence intervals for the mean survival time of each group.
