Question: Example, was about the relationship between hormone therapy and invasive breast cancer. One of the results reported in the paper was, "Absolute excess risks per 10,000 person-years attributable to estrogen plus progestin were 8 more invasive breast cancers" (Writing Group for the Women's Health Initiative Investigators, 2002, p. 321). In other words, for every 10,000 "person-years" of women taking the hormones instead of a placebo, there would be eight additional cases of invasive breast cancer. Discuss practical versus statistical significance in this situation.

Example: Breast Cancer Risk Stops Hormone Replacement Therapy Study On July 17, 2002, the Journal of the American Medical Association published the results of a study that affected the lives of millions of women. The study was the first large randomized experiment to test the effects of combined estrogen and progestin, the most commonly prescribed hormone replacement therapy for postmenopausal women.
