The standard deviation of the sampled containers' contents is 0.36
<h3>How to determine the mean</h3>
- Data = 20.72, 20.6, 20.71, 20.92, 19.79, 20.93, 20.09, 20.27, 20.49, 20.2
- Number of data (n) = 10
- Summation of data = 20.72 + 20.6 + 20.71 + 20.92 + 19.79 + 20.93 + 20.09 + 20.27 + 20.49 + 20.2 = 204.72
- Mean (μ) =?
Mean = summation of data / number
μ = 204.72 / 10
μ = 20.472
<h3>How to determine the standard deviation</h3>
- Data = 20.72, 20.6, 20.71, 20.92, 19.79, 20.93, 20.09, 20.27, 20.49, 20.2
- Number of data (n) = 10
- Mean (μ) = 20.472
- Standard deviation (σ) =?
σ = √[[(x₁ - μ)² + (x₂ - μ)² + (x₃ - μ)² + (x₄ - μ)² + (x₅ - μ)² + (x₆ - μ)² + (x₇ - μ)² + (x₈ - μ)² + (x₉ - μ)² + (x₁₀ - μ)²] / n]
σ = √[[(20.72 - 20.472)² + (20.6 - 20.472)² + (20.71 - 20.472)² + (20.92 - 20.472)² + (19.79 - 20.472)² + (20.93 - 20.472)² + (20.09 - 20.472)² + (20.27 - 20.472)² + (20.49 - 20.472)² + (20.2 - 20.472)²] / 10]
σ = 0.36

Answer:
r = 1.68 ft
Step-by-step explanation:
Volume of a sphere, V = 4/3πr³
V = 20 ft³
π = 3.14
r = ?
V = 4/3πr³
20 = 4/3 × 3.14 × r³
20 = (4×3.14×r³)/3
Cross product
20 × 3 = 4 × 3.14 × r³
60 = 12.56r³
r³ = 60/12.56
= 4.7771
r = 3√4.7771
= 1.6842
Approximately
r = 1.68 ft to the nearest hundredth
