Using the normal distribution, it is found that the median of the MCAT scores was of 500.9.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
In this problem, the mean score was 500.9, hence the median score was also of 500.9.
