Considering the margin of error of a confidence interval, it is found that the correct option is:
It would be half as wide.
<h3>What is the margin of error of a confidence interval?</h3>
It is modeled by:

In which:
- s is the standard deviation.
From this, we get that the margin of error is inversely proportional to the square root of the sample size. Then, multiplying the sample size by 4, when it changes from 50 to 200, cuts the margin of error in half, making the interval half as wide.

Answer:
Step-by-step explanation:
First, you must find the slope of the line using the formula (y2-y1/x2-x1). For your problem that would be (8-0/-2-4)= -4/3.
Then, you would plug in the slope and the y-intercept into the slope-intercept formula (y=mx+b), where m is the slope and b is the y intercept (4).
Your answer would be y=-4/3x+4
I believe it would be 80

Answer:
x = 5in
y = 16in
Step-by-step explanation:
Hypotenuse: 32/8 = 4
So, x = 20/4
x = 5
y = 4*4
y = 16
