Answer: 39 in.
Step-by-step explanation:
<em>Radius</em> formula: <em>r</em> = <em>d</em> ÷ 2
<u><em /></u>
<u><em>Diameter (d)</em></u> = 32 in.
<u><em>Radius (r)</em></u> = 16 in.
<u><em>Volume (V)</em></u> = 10,000π in.³
<em>Volume of a cylinder</em> formula: <em>V = Ah</em>
<em> A = π r²</em>
<em>V = π r² h</em>
<em>10,000π = π (16)² × h</em>
<em>10,000 = 256 × h</em>
<em>h = 10,000 ÷ 256</em>
<em>h = 39.1 in. = </em><u><em>39 in.</em></u>

Answer:
we reject H₀
Step-by-step explanation: Se annex
The test is one tail-test (greater than)
Using α = 0,05 (critical value ) from z- table we get
z(c) = 1,64
And Test hypothesis is:
H₀ Null hypothesis μ = μ₀
Hₐ Alternate hypothesis μ > μ₀
Which we need to compare with z(s) = 2,19 (from problem statement)
The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region
So base on our drawing we will reject H₀
