The answer is 1,230. All you have to do is add everything on the right side you don’t have to worry about anything on the left.
The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
<h3>
Z score</h3>
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
![z=\frac{x-\mu}{\sigma }](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%20%7D)
Where x is raw score, μ is mean, σ is standard deviation
Given that:
σ = 4, μ = 56, hence
for x = 62:
![z=\frac{62-56}{4 } =1.5](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B62-56%7D%7B4%20%7D%20%3D1.5)
for x = 47:
![z=\frac{47-56}{4 } =-2.25](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B47-56%7D%7B4%20%7D%20%3D-2.25)
for x = 56:
![z=\frac{56-56}{4 } =0](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B56-56%7D%7B4%20%7D%20%3D0)
The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.

You have to plug in a random y value and use algebra to solve for x. It is impossible to do without at least one point for y.
Your answer is False!!
