(a) Find the z score corresponding to
x = 25.
(b) Find the z score corresponding to
x = 43.
(c) Find the raw score corresponding to
z = −3.
(d) Find the raw score corresponding to
z = 1.1.

(a) Find the z score corresponding to
x = 25.
Z = (X - μ) / σ
Z = (25 - 30) / 5
Z = -1
(b) Find the z score corresponding to
x = 43.
Z = (X - μ) / σ
Z = (43 - 30) / 5
Z = 2.6
(c) Find the raw score corresponding to
.
raw value of ?
Z = (X - μ) / σ
-3 = (X - 30) / 5
-15=X - 30
30-15=X
X=15
(d) Find the raw score corresponding to
z = 1.1
Z = (X - μ) / σ
1.1 = (X - 30) / 5
1.1*5=X - 30
30+5.5=X
X=35.5
