Question

A sample has M = 72 and s = 4.In this sample,what is the X value corresponding to z = -2.00?​
A)X = 70​
B)​X = 68
C)​X = 64
D)​X = 60

Quizplus · Accepted Answer

We can use the formula: z = (X - M) / s 
Rearranging, we get X = z*s + M

Substituting the given values: 
X = (-2.00)*4 + 72 = 64

Therefore, the X value corresponding to z = -2.00 is 64. Option C) is the correct answer.

A Sample Has M = 72 and S = 4
