A certain curve (that is NOT the normal curve) is shown below. The curve is symmetric around 0, and the total area under the curve is 100%. The area between -1 and 1 is 58%.
What is the area to the right of 1?
I do not know how to do this because it is not a normal curve so I don't know how to find the area to the right of 1.
symmetric around zero means the the two sides are the same shape
zero is midway between -1 and 1
42% of the area is outside the -1 to 1 zone
... 21% on either side (symmetric)
so the area to the right of 1 is 21%
To find the area to the right of 1, you can subtract the area between -1 and 1 from the total area under the curve.
Since the total area under the curve is 100%, and the area between -1 and 1 is 58%, subtracting 58% from 100% gives you the area to the right of 1.
Area to the right of 1 = Total area - Area between -1 and 1
= 100% - 58%
= 42%
Therefore, the area to the right of 1 is 42%.
