Due to the higher z-score, the correct option regarding the highest relative score is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.
<h3>What is the z-score formula?</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
The z-score measures how many standard deviations the measure is above or below the mean, hence the higher the z-score, the higher the score X is relative to other scores.
The respective z-scores for this problem are given by:
- (39 - 31)/6.1 = 1.31.
- (1136 - 1080)/67.8 = 0.83.
- (4730 - 3960)/555.5 = 1.39.
Hence the correct option is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.

For this case we have that by definition, the equation of a line in the point-slope form is given by:
Where:
: It is a point through which the line passes
m: It's the slope
We have according to the graph, that the line goes through:
We found the slope:
Thus, the line is of the form:
We substitute a point:
