Given 𝜇 = 45, and 𝜎 = 5.5. (7 points)
a. What is the raw score when 𝑧 = −1.57?
b. What is the raw score when 𝑧 = 2.09?
c. What is the raw score when −0.48 < 𝑧 < 1.4?
d. What is the raw score when −2.17 < 𝑧 < 1.79? e. What is the raw score when 𝑧 = 0.09?
a.
"x=45-1.57(5.5)=36.365"
b.
"x=45+2.09(5.5)=56.495"
c.
"x=45-0.48(5.5)=42.36"
"42.36<x<52.7"
d.
"x=45-2.17(5.5)=33.065"
"33.065<x<54.845"
e.
"x=45+0.09(5.5)=45.495"
