The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.
<h3>What is a confidence interval?</h3>
In statistics, a confidence interval is a range to estimate for unknown terms.
The most common level is the 95% confidence interval.
It can be calculated by
CI = Mean ± margin of error.
α = 1 - 0.95 = 0.05
α/2 = 0.025
z(0.025) = 1.96
We need to find the 
= 0.645
So,
= 1.96 × 0.645
CI =1.26
C.I= 28±1.2652
Upper limit = 28+1.2652
=29.2625
Lower limit =28-1.2652
=26.7348
Hence, The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.

I can’t see the picture... pls send a pic so I can solve
Answer:
Step-by-step explanation:
The square base of each prism has a side length of 18 inches. The height of each prism, h, can be found using the function, where V is the volume of the prism.
So, V = 18² × h = 324h
⇒ h = 
.......... (1)
Now, given that the total height of the box, b, can be found using the function b(h) = xh, where x is the number of square-based prisms in a specific box.
Therefore, the box having 4 square prism will have height
b(h) = 3h
⇒ b(V) = 
{From equation (1)}
⇒ (Answer)
