Answer:
(7.7981, 8.5419). The distribution of percentage elongation can be any distribution with finite mean and variance.
Step-by-step explanation:
We have a large sample size n = 56 research cotton samples. Besides, 
and 
. A 95% large-sample CI for the true average percentage elongation is given by 
, i.e., 
or equivalently (7.7981, 8.5419). The distribution of percentage elongation can be any distribution with finite mean and variance because we have a large sample.

(5/3)y-8 = (7/3)y-16
(5/3)y- (7/3)y = 8 -16
(-2/3) y = -8
y = 3*8/2
y=24/2
y=12
Umm well ill show you how I do it so if it is 67 minus 72 I would subtract the tens spot first then I would do the ones it works for me and it is easy so I hope this helped ohand the answer is -5
