Some descriptive statistics for a Set of test scores are shown above for this test a certain student has a standardized score of

Serggg [28]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The score of the student is x = 779.42

Step-by-step explanation:

Generally we can mathematically represent the z-score as

$z = \frac{x - Mean}{ stDev}$

Here x is the score of the student

substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have

$-1.2 = \frac{x - 1045.7 }{ 221.9}$

=> $-266.28 = x -1045.7$

=> x = -266.28 + 1045.7

=> x = 779.42
