A 30-year study was conducted with nearly 90,000 female participants. During a 5-year screen- ing period, each woman was randomized to one of two groups: in the first group, women received regular mammograms to screen for breast cancer, and in the second group, women received regular non-mammogram breast cancer exams. No intervention was made during the following 25 years of the study, and we'll consider death resulting from breast cancer over the full 30-year period. Results from the study are summarized in Figure 6.2. Compute the point estimate of the difference in breast cancer death rates in the two groups, and use the pooled proportion pooled= 0.0112 to calculate the standard error.
