The confidence interval for the difference p1 - p2 of the population proportion is (0.063, 0.329)
<h3>How to determine the confidence interval?</h3>
The given parameters are:
n₁ = 93; n₂ = 80
p₁ = 0.814; p₂ = 0.618
The critical value at 95% confidence interval is
z = ±1.96
So, we have:
Substitute known values in the above equation
Evaluate
This gives
CI = 0.196 ± 0.133
Expand
CI = (0.196 - 0.133, 0.196 + 0.133)
Evaluate
CI = (0.063, 0.329)
Hence, the confidence interval is (0.063, 0.329)

Answer:
Factored form is 4x(2x+3)
Step-by-step explanation:
The factors are
8x^2 ----> 2*2*2*x*x
12x -------> 2*2*3*x
GCF is 2 * 2 * x= 4x
Now we factor out GCF from 8x^2 + 12x
When we factor out GCF, divide each term by 4x
4x(2x +3)
Factored form is 4x(2x+3)
<span>No, i think the scale should be differ from one another.
The scale that is used to weigh food scale tend be designed to measure the object with smaller weight so the user could accurately measure the nutrient that they could get from the food. (which usually measured below 100g)
Scale for concrete blocks for the other hand, tend to be used for heavier objects</span>
