Using the z-distribution, as we are working with a proportion, it is found that the margin of error for the 90% confidence interval is of 0.0524 = 5.24%.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
The margin of error is given by:
In this problem, the critical value is given as z = 1.645, and since 26 out of 80 students said they would be willing to pay extra:
Then, the <em>margin of error</em> is of:

Step-by-step explanation:
We don't know how many cans Hudson bought.
We are told, he bought:
10 green balls
5 yellow balls
Each can has 2 green balls, so there are:
10/2 = 5 cans
How can we distribute 5 yellow balls in 5 cans? Simple!
5/5 = 1
Put 1 yellow ball in each can.
So, each can will have:
2 green + 1 yellow (balls)
So, each can has 1 yellow ball
Answer:
The greatest common factor (GCF) of 36 and 22 is 2.
Equation in point slope form of a line:
y-y₀=m(x-x₀)
m=slope
(x₀,y₀)=(-4,7)
m=2/3
y-7=(2/3)(x+4)
Answer: y-7=(2/3)(x+4)
