Silicone implant augmentation rhinoplasty is used to correct congenital nose deformities. The success of the procedure depends o

n various biomechanical properties of the human nasal periosteum and fascia. An article reported that for a sample of 13 (newly deceased) adults, the mean failure strain (%) was 24.0, and the standard deviation was 3.4.

Answer: (22.41, 25.59)

Step-by-step explanation:

The t-critical value with 17 degrees of freedom for a 95% confidence interval is : 2.11

Sample mean = 24

Standard deviation = 3.2

Standard error of mean = s / √ n

Standard error of mean = 3.2 / √ 18

SE = 3.2/4.2426

Standard error of mean 0.7542

Confidence interval 24-(0.7542)(2.11) = 22.41 and

24+(0.7542)(2.11) =25.59
