Substitute each value of x, calculate, and if the answer equals to the given value of y, then the point does lie on y = 2x
Point A (1, -1)
y = 2(1)
y = 1
The answer is not y = -1 as given in the question, hence point A does not lie on y = 2x
-----------------------------------------------------------------------------------------------------------
Point B (1, 3)
y = 2(1)
y = 2
The answer is not y = 3 as required, hence point B does not lie on y = 2x
---------------------------------------------------------------------------------------------------------------
Point C(-2, -4)
y = 2(-2)
y = -4
The answer is y = -4 as required. Hence, point C does lie on y = 2x
-----------------------------------------------------------------------------------------------------------------
Point D(-2, 4)
y = 2(-2)
y = -4
The answer is not y = 4 as required, so point D does not lie on y = 2x.

Correct Answer: C
The confidence interval in the form p+E is p ± E = 0.7725 ±0.435
<h3>How to rewrite the
confidence interval?</h3>
The confidence interval is given as:
0.555< p < 0.99
To rewrite the above expression in the form p+E, we use the following equations
p = (0.99 + 0.555)/2 = 0.7725
E = (0.99 - 0.555) = 0.435
So, we have:
p ± E = 0.7725 ±0.435
Hence, the confidence interval in the form p+E is p ± E = 0.7725 ±0.435
