4. 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 rst 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 below. Death from breast cancer? Yes No Mammogram 500 44.425 Control 505 44.405 Use a hypothesis test to determine whether there was a difference in breast cancer deaths in the mammogram and control groups
