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 20 (newly deceased) adults, the mean failure strain (%) was 24.0, and the standard deviation was 3.3.

(a) assuming a normal distribution for failure strain, estimate true average strain in a way that conveys information about precision and reliability. (use a 95% confidence interval. round your answers to two decimal places.)

( , )

(b) predict the strain for a single adult in a way that conveys information about precision and reliability. (use a 95% prediction interval. round your answers to two decimal places.)

( , )

(c)how does the prediction compare to the estimate calculated in part (a)? (select the answer from 1~3)

1.the prediction interval is much wider than the confidence interval in part (a).

2.the prediction interval is the same as the confidence interval in part (a).

3.the prediction interval is much narrower than the confidence interval in part (a).

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
