Question

If the area to the left of x in a normal distribution is 0.272, what is the area to the right of x? Answer: If the area to the right of x in a normal distribution is 0.272, what is the area to the left of x? Answer:

Answer 1

To answer this question, we need to remember that the sum of the total area of a probability distribution is always 1.

First case: the area to the right of x

Then, if we have that the area to the left of x in a normal distribution is 0.272, the area to the right of x is:

$A_{\text{rightx}}=1-0.272\Rightarrow A_{rightx}=0.728$

If we sum both areas, we will get 1 as the total area of this probability distribution.

Second case: the area to the left of x

Now, if we have that
