Sagot :

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.

What is the z-score formula?

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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.
