[Midterm Q10 B, C] An аrticle in Biоelectrоmаgnetics (“Electrоmаgnetic Effects on Forearm Disuse) describes a randomized, double-blind, placebo-controlled study to determine if a common pulsing electromagnetic field (PEMF) treatment could reduce bone loss after forearm disuse due to injury. Eighty injured subjects immobilized with a cast were randomly placed into four groups. A placebo or PEMF transmitter was worn on the injured forearm for 1, 2, or 4 hours per day for 8 weeks. The data below are the percent loss in forearm bone density (BD) after each patient’s treatment – with instructor modifications. Midterm Q10.png a. Suppose that the orthopedic surgeons consider 2.5% loss of bone density significant and historical data yields a bone loss standard deviation of roughly 1.5% in patients of this type. Using these two numbers, comment on the use of 20 replicates per group: too big or too small? Use Design Expert. Respond here with your answer and reason for it. b. If you were seeking 95% power to detect the numbers mentioned in part a of this problem (2.5% / 1.5%), rebuild your Question 10 design and report the required number of replicates. Respond here with a number: “_________ replicates would be enough for approximately 95% power.”
