BRAINLIEST PLEASE
Answer:
A)
Note that
Lower Bound = X - z(alpha/2) * s / sqrt(n)
Upper Bound = X + z(alpha/2) * s / sqrt(n)
where
alpha/2 = (1 - confidence level)/2 = 0.025
X = sample mean = 1723.4
z(alpha/2) = critical z for the confidence interval = 1.959963985
s = sample standard deviation = 89.55083319
n = sample size = 30
Thus,
Lower bound = 1691.355235
Upper bound = 1755.444765
Thus, the confidence interval is
( 1691.355235 , 1755.444765 ) [ANSWER]

b)
We assumed taht the distirbution of these observations is approximately normally distributed.
*******************
c)
Yes, because the values are not far away from each other.

Brianna did it right, and 552 divided by 23 is 24!
Please give brainiest if you think my answer is good :)
48 ounces is water, out of 64 ounces of orange juice. 48 out of 64 is 48/64=0.75. That is 0.75*100=75 percent.
