<h2><em>It's exactly what it says. 12/3 = 4. 4/1 = 4. Thus, 4 = 4. It's already solved.</em></h2>
Using the normal distribution, it is found that the correct option is:
In a <em>normal distribution</em> with mean
and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
In this problem:
- The mean on the Wechsler Scale is of 100, hence
.
- The standard deviation is of 17, hence
.
- Brianna had an score of 117, hence

Then:



Hence, the option d is correct.
