Silicone implant augmentation rhinoplasty is used to correct congenital nose deformities. the success of the procedure depends on various biomechanical properties of the human nasal periosteum and fascia. an article reported that for a sample of 15 (newly deceased) adults, the mean failure strain (%) was 26.0, and the standard deviation was 3.1. (a) assuming a normal distribution for failure strain, estimate true mean strain in a way that conveys information about precision and reliability. (b) predict the strain for a single adult in a way that conveys information about precision and reliability. how does the prediction compare to the estimate calculated in part (a)?
