The national rate of breast cancer among women aged 50-54 is 221 per 100,000. #Based on data from a single large hospital, a research team suspects that women #taking hormone - replacement therapy could have a rate of at least 275 per 100,000. Using R Code: Calculate the sample size required to measure an effect of at least this #magnitude with 80% power. Defend your choice of a one-sided or two-sided test. . Repeat question 8, this time testing the hypothesis that women taking #hormonereplacement therapy have a rate of at least 300, 350, and 400 per #100,000. Using the results from questions and, create a plot with hypothesized rate #on the x-axis and required sample size on the y-axis. From this plot, state a general rule between the required sample size and the effect size being tested. State this rule in a way that could be understood by a non-expert.
