Using the normal distribution, we got that expression for the z-score of her test score is

<h3>What is Normal
Probability Distribution?</h3>
it's a type of probability distribution which is symmetric about the mean, it gives data near the mean are more frequent than data far from the mean.
Given that mean =
and standard deviation =
X=73
we know that formula of z-score is

Hence Z-score can be calculated as

Using the normal distribution, we got that expression for the z-score of her test score is
