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

Step-by-step explanation:
Remember in order to find the slope intercept form on 2 points, you need these equations:
and 
To find the slope, you will need to use the first equation. In this case the equation will look like this: 
Then use the second equation, plug in the numbers, and you will get B as your answer
Answer:
