In a certain normal distribution of scores, the mean is 40 and the standard deviation is 3. Find the s-score corresponding to a score
of 54.
a. 4.67
C. 4.67
b. 18.0
d. 13.33
Please select the best answer from the choices provided

The s-score corresponding to a score  of 54 is 4.67

Step-by-step explanation:

In a certain normal distribution of scores:

Mean =

Standard deviation =

We are supposed to find  the z-score corresponding to a score  of 54.

Formula :

x=54

Substitute the values

So,

Z=4.67

So, Option A is true

Hence the s-score corresponding to a score  of 54 is 4.67

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
