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:
1. 
: p = 0.70 , 
: p > 0.70
2. Test Statistic : 0.54 , P value : 0.2946
3. Fail to reject null Hypothesis
4. No.
Step-by-step explanation:
1. Null hypothesis is 70% of children receive antibiotics.
Alternative hypothesis is more than 70% of children receive antibiotics.
2. Test statistic is calculated as;
z = 
z = 
z = 0.54
3. p value is calculated as;
1 - right tailed probability
1 - 0.7054 = 0.2946
Answer: x = 2/3
Step-by-step explanation:
The correct form of the equation is f(x) =-3x+4
Hi, to answer this question we have to join both equations:
f(x) = -3x+4
g(x) = 2
If both equations are equal:
f(x) = g(x)
So:
-3x+4 = 2
Solving for x:
Adding 3x to both sides:
-3x+4+3x =2+3x
4 =2+3x
Subtracting 2 from both sides:
4-2 =2+3x-2
2 =3x
2/3 =x
x =2/3
